Enrique Iglesias and Anna Kournikova are expanding their family once again.
The longtime couple, who are expecting their baby No. 4, are over the moon about the new milestone, with insiders sharing that they are looking forward to the newest addition while juggling life with three other kids. A source shared with People:
"They are so excited, and also spending time getting their other three kids. [They're] ready for change and controlled chaos."

Back in August, an exclusive insider revealed that Enrique Iglesias and Anna Kournikova are expecting their fourth child. They said:
"Anna and Enrique are very happy to become parents again. They have proven to be great parents to their three children, and both of them love the process. They enjoy the activities and all that goes along with raising children."
The insider continued, revealing to People that the "King of Latin Pop" stepped away from his throne and paused touring to spend more time with his children and longtime partner.

Still, the source reassured that Enrique Iglesias cares about his fans despite the shift.
"He loves his fans and loves to tour, but as he has gotten older and become a parent, it has been harder for him to leave. He will never forsake his fans, but being a dad is very important to him."
They added that Anna Kournikova — Russian model and professional tennis athlete — shared the same affection for the family, saying:
"Anna and Enrique are happiest when they are home with their family."
Enrique Iglesias and Anna Kournikova: A glimpse into their relationship and family
Enrique Iglesias and Anna Kournikova have been together for 21 years. While many couples who met on a music video set don't last long, the pop superstar and the athlete are different.
The couple first met in December 2001 on the set of Iglesias' "Escape" music video, where they had a few makeout scenes. In the video, Kournikova is seen making advances to the Grammy winner, and ultimately, they share lip-lock sequences, showcasing their chemistry.
Shortly after working together, their relationship became official. They made their first appearance as a couple at the 2002 MTV Video Music Awards (VMAs), where Enrique Iglesias was nominated for five trophies that night.
In 2007, the couple was rumored to have called it quits after the "Hero" crooner told a Swedish outlet that he was single. People, at the time, quickly quashed the speculations and revealed that Iglesias was only joking.
In fact, a month before that interview, the singer confessed that his romance with Kournikova was "the only serious relationship I've had in my life." He told People:
"The only thing I can say is that, in my opinion, Anna, whether we are together or not, would be an ideal mother."
The pair have never tied the knot and have kept their life away from the public eye, although there are moments when the longtime couple shares glimpses of their family life.
In a 2011 interview, Kournikova revealed why she and Iglesias have no plans to get married.
"[Marriage] isn't important to me. I'm in a happy relationship — that's all that matters. I believe in commitment. I believe in being open and trusting each other and respecting each other completely."
Iglesias echoed the same sentiment in a 2012 interview, where he said:
"I've never really thought marriage would make a difference. Maybe it's because I come from divorced parents, but I don't think you love somebody more because of a piece of paper. Nowadays, it's not taboo to have kids and not be married. What makes a difference is that you're a good parent, period."
Currently, Enrique Iglesias and Anna Kournikova share three children, with a fourth on the way: twins Nicholas and Lucy, 7, and a daughter, 5-year-old Mary. They live in Miami Beach.
