Chris O'Dowd and Dawn O'Porter are expecting their first baby together.
Chris, 34, and Dawn, 35, announced their happy news with a joint Ice Bucket Challenge.
In the cute video, Chris nominates Richard Ayoade, Graham Linehan and 'Baby O'Porter' before the camera pans to Dawn who pours a glass of water over her growing tummy.
Story continues after the video
Shortly after actor Chris shared the video, Dawn took to Twitter to say: "Thought we'd better mention it, before I got O'Busted!"
This will be the couple's first baby together. They married in 2012 after meeting through mutual friends in LA.
Chris is best known for starring in The IT Crowd and hit movie Bridesmaids, while Dawn is a writer and journalist. She was previously Dawn Porter, but added the 'O' when the couple got hitched.
