Kevin Dillon, Wife Have a Girl
Daughter Ava was born May 17 in Beverly Hills and weighed 6 lbs., 6 oz. "Both mother and daughter are doing well," the spokesperson said.
On April 22, Dillon and Stuart married in Las Vegas.
"The couple, who had been engaged for over a year, had been planning a formal wedding date, but Mr. Dillon's schedule with Poseidon and Entourage had made it difficult," a rep for Dillon said in a statement.
"Entourage castmates Jerry Ferrara and Kevin Connolly were present at the ceremony."
Dillon, 40, and Stuart, 28, met through a mutual friend, began dating in 2004 and got engaged the following year. "I had to fight a little bit because she wasn't all that interested in me when I asked her out," Dillon told PEOPLE last year. "But she saw things my way eventually."
In HBO's hit comedy Entourage, which begins its new season in June, Dillon plays an obscure actor whose brother is an A-list celebrity – a role that spoofs his real-life relationship with older brother Matt.
