Ant McPartlin has confirmed that he will be Declan Donnelly's best man at his wedding to fiancé Ali Astall, and he says he "can't wait".

Dec became engaged to Astall in Australia last November and speaking on The Jonathan Ross Show, Ant said he's looking forward to the big day.

"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!"

Dec spoke about the proposal, saying: "I wasn't quite sure how I was going to do it. So I took the ring with me and I was looking for the opportunity to do it and it was beautiful out there, we were on the Great Barrier Reef and we had a wonderful hotel and it was stunning everything but I just didn't quite know how I was going to do it.

"It got to the last evening and 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 went around and we watching the sunset go down and we did it there, it was lovely."
