Chris O'Dowd and his wife Dawn O'Porter are expecting their first child.
The Moone Boy star revealed the happy news while doing a video for the Ice Bucket Challenge.
He said: "I'd like to nominate Baby O'Porter," before the camera panned and showed a heavily pregnant O'Porter.
The author and TV presenter poured a small glass of water over her baby bump and her husbanded responded: "So brave!"
The couple have been married since 2012.
