Rose Byrne has welcomed her first child with Bobby Cannavale!

The two have been dating since 2012 and welcomed the arrival of baby Rocco on Monday.

Bobby shared the news on The Late Show With Stephen Colbert on Friday, saying, “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.”

Although Byrne never officially confirmed her pregnancy, we caught a glimpse of her belly at LAX in October.

Congrats to the pair!
