Chris O' Dowd met his fiancee on Facebook.

The 'Bridesmaids' star - who popped the question to presenter and documentary filmmaker Dawn Porter on Boxing Day (26.12.11) during a trip to the island of Guernsey - approached the TV star via the social networking website after a mutual friend suggested they make contact with one another three years ago.

Dawn exclusively told BANG Showbiz: "Chris introduced himself to me on Facebook. A mutual friend had told him to get in touch while I was living in Los Angeles and he was in LA and then I invited him to my 30th birthday party, and it was there that we met."

Dawn also revealed one of the things she loves most about the 32-year-old actor is that he is romantic but not over the top.

Speaking about the proposal, she said: ""Chris is very romantic. But he's also not showy, and the proposal wasn't showy, so that was nice. It wasn't a funny thing, he was asking me to spend the rest of my life with him, which is quite a serious question, so for once he was being quite serious."

With a little help from Andrex, Dawn has embarked on a campaign to convert as many people to Andrex Washlets as possible. Check out how Dawn got on with her Clean Campaign by watching her advertorial mini episodes on Channel 4.
