— -- Rose Byrne and Bobby Cannavale are expanding their family.

The Australian actress confirmed to Australia's DavidJones.com that she and Cannavale are expecting their second child.

"I'm a little tired but feeling good," she told the site after a photo shoot with her brother, George Byrne. "Everyone was very sweet on set today, and you always get a little bit more attention when you're pregnant, which is fabulous."

Byrne, 38, and Cannavale, 47, are already parents to 1-year-old son Rocco.

The "Bridesmaids" star and "Boardwalk Empire" alum have been together since 2012.
