Matt Damon welcomes baby girl

Matt Damon and his wife, Luciana Bozan, have welcomed a baby girl named Isabella.

"The baby is here. Isabella arrived yesterday," Damon's brother Kyle told People. The baby weighed in at 7 lbs., 7 oz.

This is the first child for the couple. Bozan 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."
