Chris O' Dowd is engaged.

The 'Bridesmaids' star proposed to TV presenter Dawn Porter on Boxing Day (26.12.11) on the British island of Guernsey, off The Coast of France, where Scottish born Dawn was raised.

Chris tweeted: "I'm so bored of all this happiness and sex. I'm getting married. #engaged

"Aw, thanks for all the congrats guys. Feelin the twitter love today. Very happy & lucky boy. #engaged (sic)."

Dawn also took to twitter to share the happy news, writing: "I guess he liked it, coz he put a ring on it #engaged

"At Havelet Bay on boxing day. Very happy x

"All your congratulations tweets are getting me VERY excited. Thanks guys, so glad you can all make it to the wedding. (sic)."

Dawn - who revealed the pair are considering a summer 2012 wedding - explained that Irish actor Chris proposed with an emerald ring.

She told the Guernsey Press: "The Ring is gorgeous - an emerald, as he is Irish, and green to replace a green ring of my mum's that I have worn on that hand since I was 16.

"I was very surprised, but not a single part of me thought to say no, so that's a good start. We went straight to the pub, the Ship and Crown for a bottle of champagne and a cottage pie.

"There's lots to think about. But I have a book to write before July 1 so I need to stay in control of my excitement and get that done too."
