From the editors of InStyle Words by Jennifer Davis

It seems like it's the season for celebrity babies with the past few months seeing new arrivals from Serena Williams and Irina Shayk to name just a few.

Now it seems that congratulations are in order for Rose Byrne and Bobby Cannavale! The couple welcomed their second child, People confirms. The gender and name is still unknown, but fingers crossed the information will be revealed soon.

Byrne and Cannavale are already parents to 21-month-old son Rocco Robin, who was born in February 2016. The actor is also a father to 22-year-old son Jake from a previous relationship.

The couple have remained relatively low key about their newest addition, but Byrne did confirm that was she was pregnant in August to Australia's Jones magazine. 'I'm a little tired but feeling good,' the 37-year-old told the magazine. 'Everyone was very sweet on set today, and you always get a little bit more attention when you're pregnant, which is fabulous.'

Cannavale also opened up during an interview on The Late Show with Stephen Colbert. 'We’re just really, really over the moon. We’re in bliss right now,' he said about the pregnancy.

Congratulations to these two!
