Rose Byrne, Bobby Cannavale expecting second child

Aug. 21 (UPI) -- Celebrity couple Rose Byrne and Bobby Cannavale are expecting their second child.

The 38-year-old Australian actress announced the news in an interview with the Australian magazine Jones.

"I'm a little tired but feeling good," she told the publication. "Everyone was very sweet on set today, and you always get a little bit more attention when you're pregnant, which is fabulous."

Byrne already shares 18-month-old son Rocco with Cannavale, who is also dad to 22-year-old son Jake with ex-wife Jenny Lumet. The actress said her son inspired her to take a voice role in the upcoming animated movie Peter Rabbit.

"I've always wanted to do a kids' film," she said. "And I thought it would be sweet to do one now that I've had my own child."

Byrne previously said in a 2016 interview with Australia's The Daily Telegraph that having Rocco completely changed her life.

"How can it not?" the star said. "You have this huge responsibility you didn't have before -- there's someone you have to keep alive! I also like to think Rocco has brought out better qualities in me."

"I was already becoming my parents, even before I had Rocco," she jokingly confessed. "You know how that happens? One day, you're like, 'I've turned into my parents!'"

Byrne will also star in the movie Juliet, Naked with Chris O'Dowd and Ethan Hawke, while Cannavale will play Irving in Season 3 of the USA Network series Mr. Robot. The actor will also appear in Jumanji: Welcome to the Jungle.
