Celebrity Celebrity Family Celebrity Babies Bobby Cannavale and Rose Byrne Welcome Son Rocco The couple welcomed their first child together, son Rocco, on Monday By Staff Author Published on February 6, 2016 12:05PM EST It’s a boy for Bobby Cannavale and Rose Byrne! During a Friday appearance on The Late Show with Stephen Colbert, the actor revealed that he and Byrne had welcomed a son, Rocco, on Monday, Feb. 1. The actor also joked that he had gained “28 pounds” and that he is “doing well.” Cannavale had fun describing the diaper cake gifted to him by friend Al Pacino. ” ‘For your boy!’ ” Cannavale, 45, told Colbert, imitating Pacino as he handed over the present. Neilson Barnard/Getty Cannavale and Byrne, 36, revealed the pregnancy in the fall, three years after they began dating. (The actor is also the father of a 20-year-old son — “nice grouping,” Colbert joked.) Byrne told PEOPLE last year of their relationship, “Bobby’s a great cook. He’s Cuban and he does a couple of really good Cuban dishes like arroz con pollo and Cuban cocktails. He’s better than I am. I’m the good cleaner after!” And of their sometimes overlapping careers, having now co-starred in Spy, Annie and Adult Beginners? It “is a very intense thing you can experience together,” Byrne told PEOPLE. “It’s not for everybody, but I think he’s such a great actor.” — Adam Carlson Close
