Chris O’Dowd and Dawn Porter Will Tie The Knot

Bridesmaids actor Chris O’Dowd will marry his fiancée Dawn Porter in a private ceremony in London today.

According to The Irish Mirror, the couple will wed in a secret church and afterwards celebrate with close family and friends.

Chris and Dawn have not signed any magazine deals because they want to keep it a thoroughly private event.

A guest revealed the details of the wedding and said: “The wedding is a very small affair and is strictly family and very close friends  - they know loads of celebrities but they haven’t been invited.

“Only stars that they are really great pals with are coming because they don’t want it to overshadow their big day.

“This is why they’ve been very quiet about the exact date and never confirmed exactly where they are marrying because they didn’t want lots of attention.”

Guests travelling from Roscommon arrived in London yesterday.

“There’s a small contingent from Boyle that headed across yesterday – headed up by his dad Sean,” said the source.

“They can’t wait for the wedding. It’s going to be an extremely proud moment for all of them.

“The whole town of Boyle absolutely loves him and everyone there has been chatting about it – it’s one of the biggest things to hit the town in years.”

Yesterday, Dawn revealed her pre-wedding nerves when she took to her Twitter and wrote: “Gulp.”

The TV presenter said she accidently unwrapped a wedding present and cannot figure out who sent it.

“There is going to be a moment during the wedding that I stop everything and say ‘So who sent us the toaster?’ It’s driving me nuts,” she said.

Dawn also revealed she enjoyed her last take away as a single lady.

“For someone who doesn't quite fit into her wedding dress I sure hoofed that Thai take out like it was the last meal I would ever see,” she wrote.

Guests at this afternoon’s ceremony are expected to include Caroline Flack and Father Ted writer Graham Linehan.
