Matt Damon, wife, have baby girl
Matt Damon and his wife, Luciana, have welcomed a baby girl named Isabella, PEOPLE has learned exclusively.
"The baby is here. Isabella arrived yesterday," Damon's brother Kyle told PEOPLE on Monday. Isabella was born Sunday night in Miami.
"Mother and Isabella are doing fine," Damon's rep Jennifer Allen, confirmed to PEOPLE. "The family is very happy and everyone's healthy."
This is the first child for the couple. Luciana also has a daughter, Alexia, from a previous marriage.
"He's a terrific uncle and he's going to be a wonderful father," Kyle said of his brother, Matt. "Thankfully, Lucy has some experience, so that will help. Alexia is a terrific girl. They're all really close, they'll be an intimate family."
Late last year, Damon said at a press conference that he "longed for" fatherhood. "But I've got to learn how to be a good disciplinarian," he said, "'cause I'm a professional uncle right now."
As for getting parenting tips from his best friend – and fellow new dad – Ben Affleck, Damon told PEOPLE last month, "I'm sure I'll be asking him for plenty of diaper advice."
Damon and Luciana, who met in Miami Beach in 2003 while he was filming Stuck on You, married in December in a surprise ceremony at Manhattan's City Hall.
"They were thrilled," said New York City Mayor Michael Bloomberg, who was one of the few to attend the private nuptials.
It was the first marriage for Damon, 35, and the second for Luciana, 30.
"I like Lucy a lot. They make a fantastic couple," Damon's brother Kyle told PEOPLE at the time.
Next up for Damon: He'll reprise his role as Linus Caldwell in Ocean's 13. Production is scheduled to start in July for a summer 2007 release.
Matt Damon and Luciana Damon, 30, welcomed their first child on Sunday June 11. The baby girl named Isabella weighs 7 pounds, 7 ounces.
At about 5:45 p.m. on Saturday, the couple checked into the Joe DiMaggio Children’s Hospital, part of the Memorial Regional Hospital in Hollywood, Florida. Matt was seen having a cup of coffee with a male medical professional at 10 p.m., before returning to the birthing area on the second floor.
The couple’s family gathered in anticipation of the birth. Saturday afternoon, Matt’s mom, Lucy’s mom, and Lucy’s daughter, Alexia, 7, two young cousins and a grandmother went to a museum near Parrot Jungle to pass time. They later settled in the maternity ward with their overnight bags and stayed all night until the child was born. A source close to the couple says that the new parents are now home and that the baby is "beautiful." Rep Jennifer Allen adds, "Everyone is very happy."
Matt, 35, met Argentina-born Lucy in 2003 at the Miami nightclub Crobar, where she was working as a bartender. The actor was in town filming the comedy Stuck on You. The couple married in December 2005 in a civil ceremony at New York City’s City Hall. He will next be seen in the films The Departed and The Good Shepherd.
