Lily Collins' Emily Cooper has returned with another adventure in The City of Light in Netflix's Emily in Paris Season 5, which dropped all its ten episodes on December 18.The latest chapter of Netflix's popular rom-com series sees Emily navigating the turbulent waters of her personal and professional life after she moved to Rome in the previous season. Agence Grateau secures a contract with Marcello’s family-owned luxury cashmere business, which coincides with Emily starting a relationship with Marcello Muratori, an Italian businessman, leading to this impressive move.Now that Lily Collins' Emily returned for another exciting chapter in her life in the latest season, she is not alone. Emily in Paris Season 5 featured British actor Minnie Driver (The Phantom of the Opera, Good Will Hunting), who made her glamorous debut as Principessa Gianna Grappezi di Saturnia, also known as Princess Jane. Minnie Driver's character was an old friend of Sylvie's, who was married into the Royal family.More on Minnie Driver's character in Season 5 of Emily in Paris in our story.Emily in Paris Season 5: Minnie Driver plays Princess JaneMinnie Driver as Princess Jane in Season 5 (Image via Instagram/@emilyinparis)Emily in Paris Season 5 reconnected Sylvie with an old friend, who was none other than Minnie Driver's character, Princess Jane. A chance run-in with Sylvie in Paris brought Princess Jane into the fold, who was now married into the Royal family. Princess Jane's entry into her old friend's life could not have come at a better time, as Sylvie was looking for an opportunity to expand Agence Grateu to Rome. Since Season 5 of Emily in Paris featured an extra title card for 'Emily in Rome', it was only befitting that Agence Grateu reaches the Eternal City.While Princess Jane came into Sylvie's life at the perfect moment, as the Agence Grateu owner needed some strong connections to expand her business, she harboured a shocking secret. Emily in Paris Season 5 revealed that while Princess Jane had all the right connections, she was essentially poor, which explains the sponsorships ruling her life. Additionally, her husband's death in the latter half of the season leaves her even more debt-ridden. When Sylvie flies out to support her friend during her time of need, she seems rather upset about all the debt she'll inherit after her husband's passing.Emily in Paris Season 5: Princess Jane became an equity partner in Agence Grateu View this post on Instagram Instagram PostWhile Sylvie saw an opportunity to expand her company to Rome with Princess Jane's help, Emily did not see eye to eye with the royal. Emily's worst fears come true when Princess Jane live-streams an exclusive fashion event for Muratori in Solitano, despite Emily's strict orders. Emily in Paris Season 5 takes a turn for the worse when Princess Jane's live feed transforms Antonia's hidden gem into 'Disneyland', crawling with tourists at every turn. Antonia blames Emily for destroying the 'beautiful sanctuary' and Agence Grateu loses one of their biggest client, thanks to Jane's careless action.While Princess Jane butted heads with Emily throughout Emily in Paris Season 5, she ended up becoming an equity partner in Agence Grateu. In a shocking turn of events, Princess Jane discovered that she had inherited her husband's Palazzo, which allowed her to make an impressive deal with the Four Seasons to convert it into the first Four Seasons Palazzo.After Sylvie's husband, Laurent, ends up in huge debt, threatening her very survival and the company she built from scratch, she has no choice but to make Princess Jane the "co-head of Agence Grateu."This twist in Emily in Paris Season 5 suggests that Minnie Driver's Princess Jane is here to stay and will likely return stronger if/when the show returns with another season. While Sylvie's plan to expand into Rome horribly backfired on her, this new partner will certainly create havoc in the company and Emily's life.Emily in Paris Season 5 is streaming on Netflix.For the latest scoops on your favorite TV shows and movies, follow Soap Central.
