Rose Byrne gives birth to baby boy

Actor Rose Byre welcomed a baby boy along with boyfriend Bobby Cannavale.

Cannavale made the major announcement on “The Late Show with Stephen Colbert,” reported E! online.

“I had a baby on Monday, yes. You know, I didn’t do anything. We (men) don’t do anything and I’m so tired. I think I’ve gained 28 pounds since Monday. 

I mean, I’m not kidding you. Like, this jacket fit so well, like, last Thursday. But I’ve been eating so much,” he said. The couple have named their son Rocco and he “is doing great.” 

Asked if the newborn was named after Saint Rocco, the actor shared, “Actually, yeah, patron saint of the sick... Pretty sure. Could be wrong. I’m tired.” 

Byrne and Cannavale reportedly started dating back in 2012 and have worked together on projects including Annie, Adult Beginners and Spy. It’s the first child for Byrne but Cannavale already has a 10-year-old son, Jake, from his marriage to screenwriter Jenny Lumet, which ended in 2003.
