Ant McPartlin has revealed how he can’t wait to be best man when his sidekick Dec marries his fiancé Ali Astall.

Dec was best man at Ant’s 2006 wedding to Lisa Armstrong, and Ant said he is looking forward to returning the favour.

Speaking on The Jonathan Ross Show, he said: “I can’t bloody wait! He was best man for me, I’ve been married eight years now. His speech was very good, very funny so I’ve got a lot to get him back with!” he said.

Dec got engaged to his manager Ali on an island off the coast of Australia in November last year. It was just before he and Ant travelled to New South Wales to host the most recent series of I’m A Celebrity … Get Me Out Of Here!

“We’d organised dinner on the beach and we went round to one side of the island, the only place on the island where you can see the sun set, and we just did it there. It was lovely.”

Talking about their relationship previously, Dec admitted it was ”a little strange” when the couple first got together because they had been work colleagues for so long, but said: ”It’s going good. Everything’s hunky-dory.”

Dec, who first found fame with Ant in teenage drama Byker Grove, has previously dated actress Clare Buckfield and TV presenter Georgie Thompson.

The Jonathan Ross Show is on ITV at 9.20pm.
