Rose Byrne and Bobby Cannavale have welcomed a new family member to the world.
The Australian actress, who confirmed she was pregnant with her second child in August, has given birth, a source tells PEOPLE.
The couple, who are notoriously private, hasn’t yet commented on the birth and, as of yet, the baby’s gender and name haven’t been revealed.
Bryne and Cannavale already have a 21-month-old son, Rocco Robin, whom they welcomed in February 2016; Cannavale is also dad to 22-year-old actor son from a previous relationship.
The Bridesmaids star Byrne and her actor partner have been dating since 2012. Rumours of an engagement swirled after Bryne was spotted wearing a diamond ring on her finger earlier this year.
Speaking about son Rocco at the Met Gala earlier this year, Bryne revealed she had barely left the house since giving birth.
“It takes an hour and 45 minutes to get out of the house with a baby, and by the time I’m ready, I’m exhausted,” she said of being a new mum.
“I have a new appreciation for motherhood having just become a parent. Really, I’ve turned around a lot. I’m tired, but even so, all of it’s great. But you definitely go into a cocoon.”
