Matt Damon and his wife Luciana Barroso are the proud parents of four daughters: Alexia, 27, Isabella, 20, Gia, 17, and Stella, 15
The Odyssey star first became a girl dad after he and Luciana married in December 2005, and Matt adopted Alexia, whom Luciana welcomed with her ex-husband Arbello Barroso.
"I jumped into the deep end with Lucy. I mean, Alexia was already four. I was an extra dad," he told Parade in December 2011 about becoming a stepfather to Alexia.
He added: "The only way I can describe it – it sounds stupid, but at the end of How the Grinch Stole Christmas, you know how his heart grows, like, five times its size? Everything is full. It's just full all the time."
Speaking of his path to fatherhood, Matt said: "It was very different, it's true. But I can't imagine my life having not gone down that road. I can't imagine what my life would be now. I don't want to imagine it."

Alexia Barroso, 27
Alexia, born in Argentina in 1999, was a big factor in Matt falling for Luciana when they met at a Miami bar she was working in while he was filming Stuck on You in 2003.
Being a single mom at the time, Luciana turned down his offer of a date, and that just made Matt fall for her more.
"I was like, 'I can't, I have a four-year-old daughter, I'm not going anywhere'… and that was one of the things he loved, that I had a daughter," she recalled in a 2018 interview with Vogue.
"He said, 'I love that you're a mom and that's your priority.' Some guys might have been different, they might think it's complicated, but for him it wasn't."
Matt and Alexia have a very close relationship, and she has even worked on some of his films, including 2021's The Last Duel and 2024's The Instigators, after falling in love with film and becoming a cinematographer.
"She's done about 12 movies," Matt proudly told E! News recently. "[She's] worked on the camera team all over the world."
Alexia even appeared opposite Matt in 2009's We Bought a Zoo, making a cameo as a member of the zoo staff.

Isabella Damon, 20
Isabella was born in Miami, Florida, on June 11, 2006, and according to Matt, she's one of his biggest critics.
"If the reviews come out and they're terrible, then she'll watch it," he told E! News in July 2021. "If they come out and they're good, she's going to pass ... She's looking for ammunition all the time."
"She's like one of the funniest people I've ever met," he added. "She's really cool."
Isabella graduated from her Brooklyn-based high school in 2024 and now attends NYU, where she appears to be honing her writing skills.
"I have one who's at NYU now, who's a fantastic writer, so I could see her following me into screenwriting," he told E! News of Isabelle when asked if his other daughters are planning to follow in his footsteps.
While she likes to give her dad a hard time about some of his movies, like her siblings, Isabella is very supportive of Matt and joined him at the London and NYC premieres of his movie, The Odyssey, in July 2026.
"We are seasoned travelers in our family, just because I work all over the world. So my kids love to travel," he told People in June 2026.

Gia Damon, 17
Matt and Luciana became parents to a third daughter on August 20, 2008, when Gia was born in Miami.
After Gia's birth, Matt revealed that he and Luciana make a conscious effort to raise their daughters to care about the world. "The way you have to parent them is to show them the world. Explaining the world can only go so far," the actor said in 2008 of involving his daughters in his charity work.
"You can read about devastation every morning – it's on the front page of the newspaper – but when you actually go there and see it, you realize this isn't something you can turn the page on."
Gia also likes to poke fun at her dad. During the New York premiere of his movie The Rip in January 2026, Gia was caught on camera mocking Matt's awkward red carpet posing, asking: "Why are you standing like this?" and imitating his hunched stance. Matt took the joke in his stride, mimicking and exaggerating the pose, and grinning.
That same month, Matt recalled a sweet moment with Gia, who's still in high school, after she broke her collarbone and asked her dad to brush her hair. "I hadn't brushed her hair [in] I don't know eight, nine, years?" he said on Travis and Jason Kelce's New Heights podcast. "I don't remember when I brushed her hair for the last time...The changes are so incremental that you don’t realize."

Stella Damon, 15
Stella, who is still in high school, was born in New York City on October 20, 2010, arriving earlier than expected. "It's been pretty crazy," Matt told People shortly after Stella's birth. "The baby came a couple of weeks early. It's our fourth, so we've done it before — but it's a whole new dynamic."
Matt never thought he would be a father to all girls, but he said he has learned so much being a girl dad.
"I never expected to be surrounded by girls, but it's great… You never know which way life's going to take you," he said on TODAY in 2012.
"I'm learning so much, not the least of which is how much smarter girls are. I operated under the assumption that us guys had a chance, but I realized when I was completely wrapped around my [toddler's] finger, and she knew it."
He added: "If they can do that to us at two years old when they're fully grown, we really don't stand a chance."
