The 36-year-old television presenter, Dawn O'Porter, who is married to actor Chris O'Dowd - gave birth to the couple's first child, Art, last Sunday, Jan 25.
Joking about the news on Twitter, Chris wrote:
She wrote: "Thanks all. He is one week old today. It's been a beautiful week. I think we'll definitely keep him;) (sic)."
The 'Bridesmaids' star met Dawn through mutual friends at her 30th birthday party and wed the brunette beauty in a low-key ceremony in June 2012, when she decided to change her surname, Porter, to O'Porter, to acknowledge their nuptials formally.
Dawn previously revealed she would be giving birth to their first child in Los Angeles because it is where they currently live, despite neither of them being from America.
She said: "We're having our baby in America definitely, but I don't know where we're going to be living in five years. It's nice that we travel all the time and we love living in LA. That's totally home. But London or Ireland is also another opportunity."
