Add dad to his resume! Chris O'Dowd and his wife Dawn O'Porter have welcomed their first child together, both confirmed on Twitter on Sunday, Feb. 1. The little boy was born exactly a week ago on Jan. 25, and his name is Art O'Porter.

The St. Vincent actor, 35, posted about his first son on Twitter, along with a Photoshopped image of a baby with a beard. 

His wife, 36, also tweeted, "Thanks all. He is one week old today. It's been a beautiful week. I think we'll definitely keep him;)." 

O'Dowd announced he and O'Porter were expecting while taking part in the ALS Ice Bucket Challenge back in August.

"I've been nominated by a bunch of bloody idiots. So I guess it's time," O'Dowd said in a video posted via Twitter. "I'd like to nominate Baby O'Porter."

O'Dowd and the actress producer met at a dinner party in 2009 and married in August 2012 following a seven-month engagement. In June 2013, O'Porter (who changed her last name from Porter to O'Porter after their wedding) admitted that meeting the Irish actor helped her feel better about her career dry spell.

"I thank God I met Chris when all that was going on, because if I hadn't I might have really hit rock bottom," she told the Daily Mail. "We got together just as Chris' career was taking off, so we experienced it together. Because it was all happening for him, I still got to live this amazing life."
