All hope it’s not ‘Bad Neighbours’ in reality for Rose Byrne, Bobby Cannavale and little Rocco

Now that Australian actress Rose Byrne has given birth to baby boy Rocco, all are expecting she and partner Bobby Cannavale won’t be hounded by “Bad Neighbours.” Cannavale announced the good news on “The Late Show with Stephen Colbert” on Friday night (New York Time) while promoting his new HBO series “Vinyl.”

This is Byrne’s first child and Cannavale’s second. The Broadway actor was previously married to screenwriter and actress Jenny Lumet. With her, Cannavale had a son, Jake Cannavale. Jake and his father played father and son onscreen during the fourth season of “Nurse Jackie.”

“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,” the 45-year-old “Vinyl” star told Colbert.

According to The Sydney Morning Herald, Cannavale mentioned on the show how his “idol” and friend, the legendary Al Pacino, surprised him with a diaper cake to celebrate Rocco’s birthday.

“It was so sweet … it was a big cake made out of diapers. [He said:] 'it's for your boy,’” Cannavale said.

Byrne and Cannavale started dating in 2012 and have went on to star in various movies together such as “Spy,” “Adult Beginners” and “Annie.” Byrne had earlier to People magazine how much she enjoys sharing onscreen space with her partner, who she believes is a great actor. She said it’s an intense thing one can experience together. However, Byrne also warned it’s not for everybody.

Last month, reports surfaced about Byrne expecting her first child. She was photographed wearing a loose dress and a swollen belly. However, confirmation came in November via an Instagram photo. The photo showed the “Bridesmaid” star and her growing baby bump with “Girls” creator Lena Dunham and comedians Julia Louis-Dreyfus and Amy Schumer.

Byrne’s “X-Men: Apocalypse” is due to release in May. She will also be seen onstage at the Roslyn Packer Theatre in 2016 for the Sydney Theatre Company's production of David Mamet's Speed-The-Plow.
