Olivia Munn sneakily debuted her baby bump on her social media.

The pregnant actress, who is expecting her first child with boyfriend John Mulaney, took to Instagram Story on Friday to post video of herself talking about her partnership with Petco.

Earlier this month, Mulaney revealed that he and the 41-year-old actress are expecting a baby together during a chat with longtime friend Seth Meyers on Late Night.

The comedian opened up about his challenging past year -- which included a drug relapse, rehabilitation, and a divorce from Anna Marie Tendler, sharing how Munn "held my hand through that hell."!

Back in 2019, when Munn opened up to ET about her outlook on kids and marriage. .
