Rose Byrne and Bobby Cannavale Welcome Baby Boy

Bobby Cannavale and Rose Byrne are officially parents! On Monday the couple, who has been dating since 2012, welcomed a son, whom they named Rocco. Bobby shared the exciting news during a visit to The Late Show With Stephen Colbert on Friday, telling the host, "I had a baby on Monday, yes." He went on: "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."

While Rose never officially confirmed her pregnancy, we first got a glimpse of her baby bump back in October at Los Angeles International Airport, as well as on the set of Neighbors 2. Most recently, Rose stepped out to support Bobby at the premiere of his new HBO show, Vinyl. Congratulations to the couple on their new bundle of joy!
