Brooke Logan was the daughter of Stephen and Beth Logan, raised in Los Angeles' San Fernando Valley with her sisters, Donna and Katie Logan, and their brother, Storm Logan. Stephen had abandoned the family many years earlier, so Brooke worked alongside Beth as a caterer while studying chemistry in college. In the premiere episode, Brooke was almost raped. Policeman Dave Reed investigated, and soon Brooke and Dave began dating. Brooke met Caroline Spencer, who was engaged to wealthy playboy Ridge Forrester. Brooke was intrigued by the upper-class life, and fell for Ridge while catering a Forrester party, causing Brooke to break off her engagement with Dave.
Caroline and Brooke became friends, although when Ridge wrote Caroline a letter apologizing for his pre-wedding fling, Brooke intercepted the letter. Ridge started dating Brooke, while Caroline reluctantly moved on with Ridge's brother, Thorne Forrester. Brooke lost Caroline as a friend when Brooke confessed to hiding Ridge's letter. Meanwhile, Ridge asked Brooke to move in with him, though she initially turned him down. Brooke was insecure about Ridge's lingering feelings for Caroline, but overjoyed when Ridge proposed. However, when Brooke miscarried Ridge's baby, the wedding was postponed.
Caroline wanted Ridge back, and eventually divorced Thorne. Brooke was shocked when Ridge announced his engagement to Caroline. Ridge's father, Eric Forrester, who after 30 years was ready to divorce his wife, Stephanie Forrester, took a shine to Brooke. Eric had been involved with Beth, but Stephanie had manipulated a reunion between Beth and Stephen and sent them to Paris. So Eric pursued Brooke, and soon Brooke was carrying Eric's child. But Brooke flew to Paris for an abortion when she mistakenly believed Eric was returning to Stephanie. Eric followed Brooke and proposed to her, though Stephanie did her best to stall her divorce from Eric.
Caroline was stricken with leukemia soon after marrying Ridge, and confided in Brooke. Caroline wanted her illness to remain secret, asking Brooke and doctor Taylor Hayes to watch over Ridge once Caroline was gone. Brooke agonized before finally telling Ridge about Caroline's condition, and Caroline soon passed away. Eric moved Brooke into a posh condo. Stephanie continued to put roadblocks in Eric's way, but Brooke and Eric were married just in time to give their son a name: Eric Forrester, Jr. (Rick).Unbeknownst to Eric, Brooke pined for Ridge during their marriage, even as Ridge dated Taylor. Brooke was hired as a chemist at Forrester Creations to invent a formula that would make their couture wrinkle-free. Brooke worked with Ridge and created the BeLieF formula. Brooke and Ridge got carried away celebrating and made love on the lab floor, not knowing that Stephanie's hidden cameras were capturing every moment. Brooke and Ridge made love again when they saw a letter forged by Stephanie declaring that Eric wanted Stephanie back. Brooke asked Eric for a divorce and agreed to live with Eric two more months, during which time Brooke behaved like a brat to turn Eric off.
The day of Ridge's wedding to Taylor, Brooke discovered she was pregnant, unsure of whether Ridge or Eric was the father. Brooke annoyed Taylor by continually making her presence known to Ridge. Brooke told Ridge she still loved him, but Ridge rejected her, and Brooke stormed off to the Big Bear cabin, where she went into labor. Ridge found Brooke and delivered her baby with Taylor as a midwife via telephone. Brooke named the baby Bridget after herself and Ridge. Eric's new paramour, Sheila Carter, tampered with the paternity test, which named Ridge as Bridget's father. Brooke hired Sheila as her children's nanny and visited Ridge with Bridget as frequently as possible.
Brooke pressured Ridge to leave Taylor. Ridge didn't, so Brooke dated attorney Connor Davis to annoy Ridge. Meanwhile, the Forresters realized they hadn't signed a contract with Brooke over the development of BeLieF, and Ridge was asked to sweet-talk Brooke into signing over control of the formula. When Brooke learned of Ridge's deception, Brooke took Connor's advice and demanded 51% of Forrester in exchange for relinquishing her rights to BeLieF. Stephanie and Brooke smacked each other in the meeting. But Brooke now had controlling interest in the company, and installed Sheila as her liaison. Brooke delighted in kicking longtime enemy Stephanie out of her office.
Brooke used her new power to create a successful Forrester men's line. Ridge got close to Brooke to convince her to return control of Forrester. Ridge accidentally knocked Brooke unconscious when he playfully pushed Brooke into the Forrester pool. Brooke recovered and lobbied for Ridge to go overseas with her to start up an international branch of Forrester, but Thorne took Ridge's place. Ridge found himself a widower again when Taylor was presumed dead in a plane crash. Brooke began dating James Warwick. James and Brooke were engaged, but Ridge confronted Brooke and popped the question himself. Brooke and Ridge were married in a lavish ceremony on the beach.
While on their honeymoon, Brooke and Ridge met Prince Omar, who offered the hospitality of his Moroccan palace. But Omar simply wanted to show Taylor, who had survived and recovered from amnesia at the palace, that Ridge had moved on with Brooke. Later, at home, Ridge was blinded in an accident at the lab and aided by a British hospital volunteer. Brooke thanked the volunteer, who then took off a disguise and revealed herself as Taylor. Brooke tried to keep Taylor's existence from Ridge. But after Taylor appeared on Ridge's doorstep, a judge declared Brooke's marriage to Ridge invalid. Brooke was relieved when Ridge divorced Taylor and wanted to remarry Brooke.
Once Sheila's criminal past was revealed, Sheila held Brooke and the Forresters at gunpoint. Brooke stood between Stephanie and the gun, saying that Sheila would have to shoot Brooke first. After Sheila was paroled, Sheila wanted to renew her friendship with Brooke, who forcefully rejected Sheila out of respect for the Forresters. Soon, a letter turned up suggesting that Brooke had fixed Bridget's paternity test. A second test revealed that Eric was really Bridget's father. When Ridge wasn't convinced of Brooke's innocence, Brooke gave in to Stephanie's badgering and left for Paris, then disappeared. Stephanie and Eric sought custody of Rick and Bridget while Ridge searched for Brooke.
Ridge found Brooke wandering around Barbados with no memory, clutching two dolls she thought were Rick and Bridget. Ridge got Brooke home, where she was diagnosed with "brief reactive psychosis." When Stephanie wouldn't relinquish custody, Brooke took her kids and ran. Stephanie had Brooke arrested. But Stephanie was slowly losing her mind thanks to Sheila's mercury poisoning and found herself in the hospital. Brooke rallied at Stephanie's bedside and helped rouse Stephanie from her catatonic state.
Brooke and Ridge befriended Grant Chambers, a new designer at Forrester. After Ridge spied a kiss between Grant and Brooke, Ridge proposed to Taylor during a fashion show. Brooke rebelled by marrying Grant, although their marriage was invalid because the sea captain who performed the ceremony was a fraud. Brooke put Grant in a position of power at Forrester, and, one night, Grant was shot. Grant accused Ridge, but before Ridge's sentencing, Grant revealed to Ridge that preteen Rick had pulled the trigger. Brooke was horrified because she hadn't fully noticed the descent into heavy metal and violent video games that had caused angry Rick to break from reality. Rick had no memory of the shooting, and Ridge took the blame to protect the boy.
While Ridge was in jail, Taylor discovered she was pregnant with Ridge's child. Thorne, who was in love with Taylor, worked with Brooke to convince Taylor to lie and say her baby was Thorne's instead. Brooke announced that she was pregnant as well. On Brooke's wedding day, Brooke changed the time of the ceremony to prevent Taylor from telling Ridge the truth. During Ridge and Brooke's honeymoon, Brooke reported that she'd had a miscarriage. Taylor had her baby and introduced the child to Ridge, who was disgusted with both Taylor and Brooke for their parts in the deception. Ridge asked Brooke for an annulment and returned to Taylor.
Brooke was incensed when the underaged Rick took an interest in his babysitter, Amber Moore. Brooke tried to buy Amber off, but by then Amber was pregnant with Rick's child. Meanwhile, Brooke stepped up her pursuit of Ridge, working with Pierce Peterson, who had a yen for Taylor. Brooke tried to make Ridge jealous by dating Pierce and Genoa City's Victor Newman right in front of him, but it didn't work, so Brooke created the sexy Brooke's Bedroom line and turned the Forrester showroom into a boudoir, modeling the showstopper lingerie herself. Stephanie confronted Brooke and they tussled on a bed while live television cameras were rolling.
The Forresters were outraged when Brooke started seeing Thorne. Stephanie had a stroke and terrorized Brooke by punching her, choking her, and threatening her with a fire poker. Thorne married his ex-wife, Macy Alexander, to keep Stephanie from having another stroke, but Thorne couldn't forget Brooke, who met with Macy to expedite Thorne's divorce. Macy drove off, but Brooke jumped in the car with her. Macy deliberately drove recklessly to scare Brooke and hit a tanker. Thorne rescued Brooke, but before he could get to Macy, Macy's car exploded. At Macy's funeral, Macy's family exposed Brooke's continuing relationship with Thorne, and Stephanie had a second stroke.
Brooke and Thorne were married, but Ridge tricked Brooke into admitting she'd always love Ridge, with Thorne in earshot. Thorne got an annulment, and Brooke resumed her pursuit of Ridge. Soon, Brooke got a call that her father, Stephen, was dying, so Brooke moved to Paris to be with him. Brooke didn't know that Massimo Marone, Ridge's secret long-lost father, had offered Stephen five million dollars to help him get Brooke out of Ridge's life. Brooke went on a blind date and fell from the Eiffel Tower, prompting Ridge to rush to her side. Brooke's mother, Beth, exposed Massimo's scheme, and Brooke turned her back on Stephen.
Brooke was concerned when Deacon Sharpe married her daughter, Bridget, to mess with the Forrester family. When Brooke unexpectedly connected with Deacon, they began a prolonged affair, during which Brooke got pregnant. Stephanie exposed Brooke's pregnancy at a press conference, where Whip Jones claimed he was the father. Brooke accepted Whip's proposal to keep Bridget from learning the truth, but the marriage was a failure, and later, Bridget overheard Brooke and Deacon discussing their affair on a baby monitor. Bridget confronted Brooke, but Brooke went into labor. Stephanie helped Bridget deliver Brooke's baby. Afterwards, Bridget shunned Brooke, but Stephanie helped Brooke turn over a new leaf, and Bridget suggested naming the baby Hope.
Eric helped Brooke with Hope. One night, Brooke walked into Eric's living room and found Eric and Taylor being held at gunpoint by an escaped Sheila. When Sheila aimed at Brooke, Taylor lunged for the gun and was shot. Eric and Brooke jumped Sheila, but Brooke was also shot in the struggle. While Brooke recovered, Taylor died in Ridge's arms in the hospital. Brooke consoled Ridge, but when grief counselor Tricia Quick told Brooke to stay away, Brooke dumped spaghetti sauce on Tricia. Ridge was floored learning about Brooke's affair, but more so learning that Massimo was his father. Ridge and ex-sister Bridget kissed, and Brooke accused Bridget of trying to pay her back for Deacon.
Brooke dated Ridge's new half-brother, Nick Marone, but after Ridge bought Spectra Fashions and gave it to Brooke as Logan Designs, Ridge and Brooke remarried in the jungles of South America. Brooke panicked when Sheila kidnapped Ridge to extort money from Massimo. Brooke hid in the trunk of Sheila's car and found Nick with Ridge at the kidnap site. Brooke and Massimo stormed Sheila, but in the ensuing melee, Ridge fell into a furnace. Brooke and Nick grieved together and ended up making love. Brooke was overjoyed when Ridge turned up alive, but horrified not knowing if Ridge or Nick had fathered her new baby. Brooke annulled her marriage to Ridge when a botched paternity test named Nick as the father.
During Brooke's wedding to Nick, Ridge burst in with the erroneous news that Nick had been cheating, setting off a chain of events that resulted in Nick and Massimo being arrested by the FBI for shady business dealings. A second paternity test revealed Ridge as the father of Brooke's baby, which she named Ridge Jr. (R.J.), and Ridge and Brooke remarried, with Brooke stepping in as a mother to Ridge's older kids, Thomas, Steffy, and Phoebe.
Brooke got caught in the middle of a power struggle between Ridge and Thorne at Forrester Creations. Meanwhile, Amber, who wanted revenge on Ridge for breaking up her relationship with Thomas, showed Brooke a misleading photo of Ridge and Bridget, playing on their former feelings. Amber also trapped Ridge and Bridget in a mineshaft rigged with hidden cameras, hoping they would kiss. Instead, Ridge and Bridget almost froze to death, after which Brooke smacked Amber. Ridge disappeared, and later Brooke received a voice mail from Ridge saying he was leaving her. It turned out that Morgan DeWitt, who had previously terrorized Ridge and Taylor, saw an opportunity when Ridge fell and lost his memory. Amber found Ridge with Morgan in Venice, Italy, and alerted Brooke to Ridge's whereabouts. Brooke helped Ridge regain his memory.
Brooke was concerned when Ridge was gone all night. Ridge came home and told Brooke there was a wax dummy in Taylor's coffin: Taylor was alive. Ridge and Taylor explained that Omar had spirited Taylor away from the hospital and healed her in his palace. Brooke was relieved when Ridge stayed with her, even as a judge maintained Ridge was still legally married to Taylor. Stephanie had a heart attack and begged Ridge to reunite with Taylor as her dying wish, so Ridge and Taylor renewed their vows. But Brooke suspected Stephanie had faked the attack, and even yanked the tube out of Stephanie's ventilator, daring Stephanie to die. Ridge stayed married to Taylor, even after Stephanie was exposed and the family turned their backs on her. So Brooke turned her attentions toward Nick, even though by then Nick was already married to Bridget.
Bridget saw a close moment between Brooke and Nick, so Bridget lied that she had aborted Nick's baby. Stephanie gave Brooke a gun as a gift and told her to shoot herself. Brooke shot at Stephanie instead, but missed. Brooke dated Dante Damiano to prove to Bridget she wasn't interested in Nick. But Stephanie saw Brooke with Nick and planned to tell Bridget. Tired of Stephanie's interference, Eric divorced Stephanie and married Brooke to make her unavailable to Nick. Stephanie, who had found out she was the sole owner of Forrester, fired Eric for knowing about it, and also terminated Brooke. Ridge and Brooke considered forming their own company, upsetting Taylor. Eric and Brooke annulled their unconsummated marriage, and Brooke encouraged Nick to stay with Bridget and raise Bridget's baby.
Ridge's marriage to Taylor imploded after Taylor admitted she'd kissed Hector Ramirez, and had slept with James many years before. Ridge called Taylor a hypocrite for always judging Brooke while hiding her own secret. Ridge was still in love with Brooke, but Brooke wanted to be with Nick, who was now free. When Ridge pressed the issue, Brooke blurted out that she wasn't going to let another man abandon her like her father did. So Brooke was stunned when Ridge brought Stephen back from Paris to mend fences with Brooke. Having taken antianxiety pills to deal with the stress, Brooke was out of it and unable to consent to making love when Ridge came on to her. Ridge was horrified to realize he had unintentionally raped Brooke.
Brooke stayed with Nick. But when Ridge had a heart attack, Brooke was amazed to find Stephanie trying to reunite her with Ridge. Stephanie even gifted Brooke with 50% of Forrester Creations. Stephen wangled Taylor's 2% share out of her and gave it to Brooke, who again had controlling interest. At Nick's urging, Brooke fired Ridge and Stephanie, but later relented. At a fashion show, Ridge kissed Brooke on the runway to get at Nick. Stephanie found nude photos Brooke had taken for the Bedroom line and had them blown up on a billboard at the site of Nick and Brooke's wedding to turn Nick off from Brooke. But the ploy failed, and Nick married Brooke anyway.
Ridge flirted with Brooke's sister, Donna, to make Brooke jealous. Later, Donna spied Ridge and Brooke kissing and told Nick, who had a one-night stand with Bridget. When Bridget turned up pregnant, Brooke pushed Nick overboard from his boat and ran back to Ridge. After Nick's mother, Jackie Marone, went over a balcony railing during an argument with Stephanie, Nick told the Forresters that the only way to keep Stephanie out of jail was to give him control of Forrester. Eric, Ridge, and Brooke started a new company, Forrester Originals, and Ridge proposed to Brooke at their first press conference.
Tensions rose as Brooke's son, Rick, started dating Ridge's daughter, Phoebe. On a business trip to Australia, Ridge punched Rick after finding him with Phoebe, causing Brooke to leave Ridge. Brooke was jealous when Ridge dated Genoa City transplant Ashley Abbott. But when Shane McGrath, who had been bothering Phoebe, turned up dead, Nick was arrested while Ridge took a mysterious business trip. Brooke overheard Stephanie's phone call to Ridge and got Stephanie to confess the truth: Shane had shot himself in front of Ridge, but, because of Ridge's prior record after taking the rap for Rick regarding Grant's shooting, Ridge disposed of Shane's body, and Stephanie helped Ridge frame Nick. Stephanie choked Brooke with a phone cord and held Brooke at gunpoint to keep her from going to the police.
Brooke convinced Stephanie to come clean, and Ridge went to jail. Taylor worked with Rick to help him remember shooting Grant, since Rick's recollection was the only thing that could free Ridge. For Phoebe's sake, Rick testified that he had shot Grant, but never actually remembered pulling the trigger. Later, Brooke accidentally left Hope and R.J. alone all night after Brooke fell asleep in her car. Child Protective Services were brought in when Hope and R.J. later set fire to the living room while Brooke's back was turned. When Ridge moved for custody, a despondent Brooke confided in Andy Johnson, who she'd met at a restaurant. Stephanie encouraged Andy to pursue Brooke and even told Andy where to find Brooke's spare key. But Andy had been stalking Brooke, and before long, Andy got into the house and raped Brooke.
Ridge returned custody of the children to Brooke, which aided in her recovery. But Brooke was experiencing flashbacks and nightmares, so when Brooke was scheduled to model the slinky lingerie of the Brooke's Bedroom line, Brooke had a meltdown on the runway, causing her to seek counseling. Stephanie was horrified that she had played a part in Brooke's rape and begged Brooke's forgiveness, but Brooke raged at Stephanie and threw her out.
Taylor and Nick had married and wanted a child, but Taylor had fertility issues, so Taylor was implanted with a donor egg. Taylor had a healthy child, whom she named Jack, after her father, but Taylor wanted to know the identity of her egg donor. Bridget, who had overseen the in vitro process, was forced to admit there had been a mix-up in the lab and that Brooke was Jack's biological mother. Brooke had trouble denying her connection to baby Jack, infuriating Taylor, who had her own trouble bonding with the child. Taylor started drinking heavily upon learning that Nick still loved Brooke. Nick filed for custody, and Brooke endangered her relationship with Ridge by helping Nick.
When Taylor started seeing Rick, Brooke threatened to ruin Taylor's chances at custody. Ultimately, Nick and Taylor were awarded joint custody, but Taylor still couldn't bond with Jack, so Taylor asked Brooke to raise the baby instead. Brooke and Ridge's relationship was threatened by Rick's increasing hostility toward Ridge. Rick fought with Ridge on the roof at Forrester and was paralyzed in a fall. Brooke doubted Ridge's innocence and let herself be manipulated by Rick, who wanted Ridge out of his mother's life. Rick made a move on Steffy to annoy Ridge, but, when Phoebe found out, she went off on Rick for getting involved with her, her mother, and her sister. Phoebe attacked Rick in his car, causing him to lose control, and Phoebe died in Ridge's arms. The Forresters wanted to ship Rick to Forrester International, but Brooke couldn't bear to send her son away.
Brooke and Ridge remarried on the beach where they'd had their first wedding, but the newlyweds battled over Rick's romance with Steffy. Brooke didn't realize that Rick had only seduced Steffy as revenge on Ridge; Rick felt Ridge's constant waffling between Brooke and Taylor had given Rick an unstable home life as a child. Ridge clued in and put a stop to Steffy's relationship with Rick. Soon after, Ridge and Brooke discovered a clerical error in their marriage certificate that invalidated their union. Taylor gave Ridge an antianxiety pill to relax, but Ridge secretly took more and made love to Taylor under their influence. Ridge gravitated back to Taylor, while Steffy and Thomas intercepted and faked text messages between Ridge and Brooke to make sure that Taylor's wedding to Ridge took place. Brooke found out and stopped the wedding by riding in on her horse.
Ridge admitted he loved both Brooke and Taylor, but wanted them to resolve their own conflicts before he chose between them. Brooke and Taylor tried "family counseling" with James, but the massages, foam bats, and mud baths all ended in disaster. When Ridge later reminded Brooke and Taylor how much they had helped each other over the years, the ex-wives hugged and apologized to each other. Ridge then remarried Brooke and made peace with Rick.
When Bill Spencer, Jr. took control of Forrester, Bill installed his new wife, Brooke's sister Katie Logan, as Forrester's CEO. Katie offered the power positions to the Forrester men, but, when they refused, Katie made Brooke president and Donna vice president. Ridge was furious, but Brooke helped Ridge and Eric with their plan to create the ugly Dare line in an attempt to sabotage Bill. Eventually, Steffy set up a seduction to trick Bill into signing control to her, after which she distributed the stock among Ridge, Eric, Stephanie, and even Taylor, edging the Logans out. Brooke offered to buy Taylor's 25%, but the ensuing argument ended with them fighting in a pond at Forrester.
Brooke and Ridge were thrown into further conflict when Brooke's daughter, Hope, began interning at Forrester. Steffy resented Hope, and Ridge and Brooke had differing opinions about their daughters. But Steffy especially resented Brooke, viewing Brooke as the reason her family wasn't together. At Hope's graduation party, where everyone wore identical clothes and masks, a randy Brooke lured Ridge out to the terrace for a quickie. Brooke blanched when she learned she had mistakenly made love to Hope's boyfriend, Oliver Jones. Steffy found out and said she'd go public if Brooke didn't leave Forrester. Brooke defused Steffy's bomb by explaining herself to a surprisingly forgiving Ridge, who forced Steffy to create a tribute video to Brooke as punishment.
Steffy's grudgingly sincere attempt at the tribute was sabotaged by Spencer Publications to expose Brooke's encounter with Oliver. Hope was heartbroken, and Stephanie double-slapped Brooke for hurting another daughter. During a separate argument, Stephanie fell, and Brooke initially thought Stephanie was faking another medical condition. But Brooke accompanied Stephanie to the hospital and learned that Stephanie had Stage IV lung cancer. Brooke begged Stephanie to tell the family and seek treatment, but Stephanie was resigned and wanted to enjoy her remaining time instead. Brooke found herself on a roller coaster with Stephanie as Stephanie checked off her bucket list.
Stephanie lost her mother's scarf and traced it to a homeless woman, Dayzee Leigh. Brooke found Dayzee holding a broken bottle on Stephanie and scared Dayzee off. Brooke lost track of Stephanie when Stephanie went after Dayzee, leaving Brooke to wander the streets of downtown Los Angeles. Brooke met Anthony, a homeless man who figured out Brooke was describing Dayzee and told Brooke where to look. Brooke was relieved when Dayzee convinced Stephanie to go in for treatment, and was even more surprised when Stephanie admitted to Brooke that she loved her. Brooke joined Stephanie in her quest to help the homeless, serving food to those in need at a soup kitchen.
Thomas wanted to resurrect the men's line and asked for Brooke's help. Taylor didn't want Brooke anywhere near her son. When Thomas feared his collection wasn't getting attention, he kissed Brooke as a publicity stunt. Ridge was upset, and told Taylor he'd return to her if anything inappropriate happened between Thomas and Brooke. An infatuated Thomas kissed Brooke while she was sleeping. Brooke scolded Thomas but got in trouble with Ridge for keeping the kiss a secret. Later, Brooke and Thomas were lost at sea in a plane crash, and Thomas saved Brooke from drowning. Brooke and Thomas washed up on a deserted island where there was nothing to eat. Half-starved, Brooke found some berries and shared them with Thomas, but the fruit produced hallucinations, and when Brooke and Thomas woke up, they couldn't be sure they didn't have sex.
After Brooke and Thomas were rescued, Thomas confessed that he and Brooke did indeed have sex. Brooke couldn't completely deny it and was filled with self-loathing, so she gave Ridge a divorce and permission to be with Taylor. On Ridge and Taylor's wedding day, Stephanie admitted she had convinced Thomas to lie about having sex with Brooke in exchange for Stephanie's 25% share in Forrester. Ridge left Taylor at the altar and reconciled with Brooke, who made Stephanie "pay" by forcing Stephanie to sing to Brooke in public.
When Rick started designing, Brooke was upset to find Amber working with him. So Brooke recruited Caroline Spencer, the niece of Ridge's departed wife, to replace Amber. Brooke hoped to pair Rick with Caroline. Taylor, however, wanted Thomas with Caroline. Brooke also spent much of her time arguing with Ridge and Taylor over Steffy and Hope, who were doing battle over Liam Cooper. Brooke encouraged Hope to lose her virginity to Liam and gave Hope sexy clothes from the Bedroom line. But when Hope had frigidity issues, Brooke took Hope to a therapist. Brooke understood how Hope's origins with Deacon were problematic for Hope, but was adamant that Hope not confront Deacon. Meanwhile, even though Brooke knew that Liam tore up Steffy's annulment papers, Brooke planned a huge wedding for Liam and Hope in Puglia, Italy, where Ridge proposed to Brooke in an olive garden.
Brooke was horrified when Hope reported seeing Deacon in Italy, and continued to campaign for Hope's on-again, off-again romance with Liam. Meanwhile, Brooke happily married Ridge for the seventh time at the Forrester mansion with the full support of Stephanie. But Brooke returned home from her honeymoon without Ridge, explaining that Ridge had left her because she had texted Deacon to stay away from Hope and lied about it. As Brooke and Ridge hadn't yet filed their license, their marriage was not valid.
Brooke was thunderstruck when Stephanie revealed that her cancer had returned and that the prognosis was terminal. Brooke and Stephanie admitted they'd always brought out the best and worst in each other, and Stephanie told Brooke she'd have to be the new matriarch of the family. Brooke busied herself by trying to help Katie, who almost died in childbirth after finding out how Bill had schemed to sabotage Hope's relationship with Liam. Brooke was furious to learn of Bill's manipulations, but came to his aid as Katie began slipping into postpartum depression.
When Katie disappeared and seemed to have fled to Aspen, Brooke accompanied Bill to the resort town only to find a package containing Katie's wedding ring and a request for a divorce. Brooke and Bill became closer as she tried to help him through his anger, and the two even enjoyed a hot-air balloon ride. What they didn't know was that Katie, in her depression, had arranged the ride, wanting Brooke to replace her in Bill's life. Lonely Brooke began seeing Bill in a new light.
Brooke attended Stephanie's "celebration of life" party, both hopeful and afraid that Ridge would show up. Stephanie and Eric headed up to Big Bear, but later, when Eric was called away to an emergency meeting, Brooke flew to Stephanie's side. Stephanie admitted that she had asked Ridge not to come to the party, preferring he not see her in her deteriorating condition. When Stephanie asked Brooke's forgiveness for the many years of hurting her, Brooke confessed that she was ashamed how her own actions had hurt Stephanie. Stephanie gave Brooke her engagement ring, then quietly died in Brooke's arms.
Bill found Brooke at the cabin and got her to open up about Stephanie's death. Caught up in the emotionality of the moment, Brooke and Bill kissed. When they returned to Los Angeles, they were shocked to find Katie there, ready to reclaim her life. Brooke and Bill swore each other to secrecy about the kiss, but Taylor, who was treating Katie, overheard and went straight to Katie with the news. Katie confronted Brooke, who was forced to admit she had kissed Katie's husband. Ultimately Katie forgave Brooke, who promised it wouldn't happen again.
Brooke was included when Katie staged an intervention on Bill for what Katie perceived as his over-reliance on alcohol. Later, Brooke found out Bill and Katie weren't having sex, so Brooke arranged a sexy night for them that backfired when Katie smelled booze on Bill's breath. Brooke defended Katie while fighting her attraction to Bill. Hope picked up on the sparks between them and reminded Brooke of her previous inappropriate interactions with men. Meanwhile, Brooke tried placate Taylor, who was angry that Stephanie had chosen to die with Brooke.
When Eric started seeing Taylor, Brooke insisted he was being taken advantage of. Brooke was surprised when Eric told her to butt out. Meanwhile, Liam was again trying to choose between Hope and Steffy, so Brooke threw Liam and Hope a surprise wedding that included the priest who officiated at their Italian nuptials. The wedding backfired when Steffy arrived and announced she was having Liam's baby.
Feeling Rick's presidency at Forrester was being threatened by Eric's sudden decision to appoint Thomas vice-president, Brooke complained to Bill about Taylor's influence on Eric. Bill suggested counteracting it by rebooting the very successful Brooke's Bedroom lingerie line. Brooke felt she was too old to resume modeling it, but Bill encouraged her after getting her to show him the lingerie she was wearing under her clothes.
With Bill's help, Brooke interrupted Thomas' sales presentation with a mini showing featuring Brooke wearing Brooke's Bedroom. Eric liked what he saw and green-lit the project. Brooke and Bill's champagne-filled celebration included heavy flirting, which Taylor saw and reported to a furious Katie. Brooke and Bill claimed innocence, with Brooke even asking Katie if she were off her anti-depressants. Soon after, Bill called Brooke over to straighten things out with Katie, but Bill, having had too much to drink, swerved into Brooke's car. Not wanting Katie to find out Bill had been driving drunk, Brooke hid Bill's car in her garage and took him home to care for his wounds. Brooke forbad Lt. Baker, whose discovery of Brooke's abandoned car prompted him to investigate, from searching the garage.
Brooke called Katie to tell her Bill was spending the night, but remained silent as to why. When Katie stormed over and found Bill in Brooke's bed, Katie took off her wedding ring and demanded a divorce. Brooke and Bill took this to mean they were free to make love. But their afterglow was interrupted by a call that Katie was back in the hospital. Brooke felt responsible for Katie's heart failure, brought on by Katie neglecting to take her anti-rejection medication. Brooke confessed Bill's accident to a disappointed Donna, who had sensed something between Brooke and Bill but kept quiet when Taylor started asking questions. After Katie woke up from her coma and asked for her ring back, Brooke told Bill they couldn't be and told him to be with Katie. Later, Taylor overheard a suspicious Lt. Baker asking Brooke about her part in Bill's accident, and, when Brooke couldn't look Taylor in the eye, Taylor deduced that Brooke had indeed slept with her sister's husband.
Brooke began experiencing hot flashes, dry skin, and other symptoms that led her doctor to diagnose Brooke with the beginning stages of menopause. Brooke had little time to process the news when the doctor also announced that Brooke was pregnant! Katie caught Brooke in the middle of an anxiety attack, but Brooke, who was afraid Katie might die if she learned the truth, managed to explain it away, later confessing her pregnancy to Donna. Taylor again confronted Brooke about sleeping with Bill, but Eric stepped in and told Taylor to back off. Feeling confident, Brooke told Taylor to watch herself, warning Taylor that if she wanted Eric back, she could have him "just like that."
Buoyed by Eric's support, Brooke confided to him that she was having Bill's baby, and asked Eric to say that he was the father to keep Katie in the dark. When Eric gently refused, Brooke arranged a "family dinner" with Rick and the visiting Bridget to remind him what their life was like as parents. Eric saw through the ruse, so Brooke upped the ante by kissing him. Eric admitted he still had feelings for Brooke and vowed to stand by her, but declined to accept responsibility for Bill's baby. Undeterred, Brooke had an exact replica of Eric and Brooke's honeymoon tent created. Eric stood his ground, though later Eric defended Brooke to the press when she refused to model for Brooke's Bedroom during a preview.
Brooke finally took Eric's advice to tell Bill and Katie the truth, but Brooke fainted before she could make the confession. In the hospital, Brooke learned that she had miscarried Bill's baby and therefore remained quiet about it. Katie threw a birthday party for Brooke and even invited Taylor, who had been amused to hear there was a new man in Brooke's life. So Brooke was shocked when Taylor arrived and exposed Bill and Brooke's affair and resulting pregnancy! Brooke didn't know that Taylor, who was furious to learn about Brooke coming on to Eric, snooped through the files concerning Brooke's recent hospital visit and sussed out the truth.
When Brooke couldn't deny Taylor's claims, Katie went ballistic. Brooke tried to remind Katie that her trying to set Bill and Brooke up during her postpartum depression had set the wheels in motion, but Katie slapped Bill and disowned Brooke, throwing them both out. Brooke shared Liam's dismay when Katie took control of Spencer Publications in her divorce proceedings. Brooke blasted Katie for the move, and Brooke's defense of Bill so infuriated Katie that she announced Stephanie had been right all along: Brooke was a slut from the Valley! Brooke smacked Katie and insisted Katie's actions would only hurt Will, but later, Donna told Brooke that she was taking the wrong tack with Katie and that she needed to try apologizing instead.
Brooke was thrilled when Katie allowed her to babysit Katie's son, Will, feeling it meant Katie was leaning toward forgiveness. What Brooke didn't know was that Katie had set up cameras to spy on Brooke and Bill, who discussed their affair and miscarriage in a few charged moments, but never crossed the line. Brooke happily flew to Monte Carlo to represent Brooke's Bedroom at a fashion event and was shocked to find Bill there: Bill had discovered the cameras, rejected Katie's reconciliation attempt, and declared his love for Brooke! Still guilt-ridden, Brooke ran off, but Bill chased her through Monte Carlo. Brooke told Bill they needed to hear Katie out before they made any decisions.
After Katie and Bill's confrontation about the cameras devolved into bitterness, Brooke fumed that Katie blamed her and Bill for everything and even accused Katie of abusing Bill! Brooke arrived home to find an amorous, towel-clad Bill. Brooke resisted, but they soon made love; the next day, Bill moved in with Brooke. Hope went off on Brooke, incredulous that her mother would want to be with a man who had worked so hard to ruin Hope's life. Later, Brooke wanted to make up with Katie but continued to hold Katie responsible for the destruction of her marriage to Bill.
Bill's long-lost son, Wyatt Fuller, took Bill to task for abandoning his family the way Bill had abandoned him, causing Bill to kick Wyatt out of the family. Brooke went to Wyatt and explained her side of what had happened between her, Bill, and Katie, then convinced Bill to make up with Wyatt. This made Bill love Brooke more, but Brooke continued to feel guilty about continuing their relationship. After Katie found out that Brooke and Bill were living together, Brooke refused Katie's demand to choose between her sister and her lover. Brooke admitted to Bill that she couldn't deny her feelings for him, and Bill responded by asking Brooke to marry him as soon as his divorce from Katie became final.
Brooke was surprised when Bill wanted to take her mountain climbing in Aspen. On Halloween, she surprised him in a sexy bear costume, but Brooke worried when Bill seemed distracted on the climb. Bill fell, surviving only because Brooke had begged him to wear a harness. Bill pledged his love, but on the way home, Brooke was hurt to hear that Bill had chosen to return to Katie. Bill later returned bragging how he had tricked Katie into signing papers that would return control of Spencer Publications and give him "joint ownership" of baby Will. Brooke was furious, and during a confrontation between Bill and Katie, Brooke replaced the papers with leaves she had brought back from Aspen. Bill begged for another chance after Brooke broke their engagement, but Brooke was more interested in healing her damaged relationship with Katie, promising her sister she wouldn't go back to Bill.
