Matt Damon and wife Luciana Barroso, 32, welcomed their second child together, a daughter named Gia Zavala, on Wednesday, a rep for the couple confirmed.
Jennifer Allen told the AP, ''Everyone is doing great and she is a healthy, beautiful baby girl.''
The baby makes big sisters out of Isabella, 2, and Alexia, 10, Luciana's daughter from her previous marriage.
Pulling a Brad Pitt and Angelina Jolie, the couple eschewed a formal pregnancy confirmation for a baby bump debut on the red carpet to announce their great expectations. Luciana sported a visibly pregnant belly while attending the Empire Film Awards with the actor in March.
Expect Matt, 37, to take some time off after his next two projects to focus on family.
"Luciana asked me to take a break from work," Matt has said. "She saw a pile of scripts, and when I told her they were the movies I was supposed to shoot in the fall, she asked me if I still wanted to be her husband."
