Rose Byrne is pregnant for the second time.

Rose made the big reveal that she and partner Bobby Cannavale are expecting their second child on the set of her JONES Spring cover shoot with brother George Byrne. The siblings were very comfortable on the set and even cracked jokes like any brother and sister.

When asked about her pregnancy Rose admitted that she was a little tired but felt good. “Everyone was very sweet on set today, and you always get a little bit more attention when you’re pregnant, which is fabulous,” Rose said.

Deborah Bibby of Jones magazine shared a teaser of the siblings’ photo shoot on Instagram. “When I chatted to one of my favourite actor’s Rose Byrne ( I saw her on stage this year in Speed the Plow) about the possibility of doing the Jones Spring cover together with her talented photographer brother George - she was super excited and so generous with her time and making this happen,” the editor wrote in the caption.

For the cover, Rose and George talked about their relationship as siblings. They shared how they backed each other, argued and bonded over their shared love for “Seinfeld.” As for their pictorial, Rose believed that working with her brother made them a good combination. George is a photographer, while she knows about the modeling side.

“There was a lot of laughing,” Rose said about their photo shoot. “We were nervous and laughing and then not nervous and laughing. George is a photographer, so he understands much more about the technical choices on a shoot than I would. But I understand more about the modeling side, so it was a good combination of the two.”

Rose gave birth to her first child with Cannavale in February 2016. They named him Rocco, E! News reported.

Rose and Cannavale started dating in 2012. The couple has maintained a low-key relationship despite working together in several projects like “Spy” and “Annie and Adult Beginners.”

In 2013 Emmy Awards, Cannavale won the outstanding supporting actor in a drama series award. On his acceptance speech, he thanked Rose and even called the “X-Men: Apocalypse” star “the love of my life.” He also thanked his family and friends.
