Rose Byrne expecting second child with Bobby Cannavale

Rose Byrne and Bobby Cannavale are expecting their second child together.

The 38-year-old actress is already mother to 18-month-old Rocco with Boardwalk Empire star Bobby, who she has been dating since 2012. And on Monday (21Aug17), Rose confirmed in an interview with Australia's Jones magazine that they will soon be adding to their family with another tot.

“I’m a little tired but feeling good,” she smiled. “Everyone was very sweet on set today, and you always get a little bit more attention when you’re pregnant, which is fabulous.”

Rose is currently filming drama Juliet, Naked, based on the Nick Hornby novel, alongside Ethan Hawke and Chris O'Dowd.

The pregnancy news comes just months after Rose sparked rumors she was engaged to Bobby when she was seen wearing what appeared to be a large diamond on her ring finger as she headed out in her native Australia last November (16). Neither Rose nor Bobby have commented on the speculation since.

The Bridesmaids star recently opened up about adjusting to life as a new mom, admitting she rarely left home in the first few months after Rocco's birth because she was so exhausted.

"I'm still in a fog," she laughed to news.com.au last year. "I haven't even left my apartment in three months."

"I'm tired, but even so, all of it's great," she gushed about motherhood. "But you definitely go into a cocoon. Sleep is what makes me feel good at the moment, wherever I can squeeze it in that's the best thing for now."

Rose also revealed she was grateful to have Bobby by her side as she has learned a great deal about parenting from the actor, who has a son from his marriage to Jenny Lumet.

"He's terrific," she smiled. "He has a 21-year old (from a former marriage) so this is old hat to him. And I have to say, having someone who's already a parent is great because this is all very, very new to me. So I'm just taking tips from him."
