Johnny Vegas' Boyle Show

The 'Benidorm' star says he's willing to act as a double for the frumpy singing sensation - who was dubbed the 'Hairy Angel' when she rose to fame on 'Britain's Got Talent' - if his comedy career ends.

Talking about a photo in which he bears an uncanny resemblance to the 48-year-old singer, Johnny quipped:"It's always good to have a back-up. I don't mind doubling for Susan."

Last year, Johnny was asked to compete on 'Strictly Come Dancing' but he thought he was only offered the role so the public could laugh at him.

He told The Star newspaper: "It's such a big commitment to do the show and I really was just so busy with other things and I just know health-wise - well, would it be good for ratings - me keeling over?

"I know how tiring it is and it's not something I have time to do at the moment, but it's nice to be asked. I think they were looking for this season's John Sergeant and I think they thought they'd found that in me."

Political reporter John Sergeant stepped down from 'Strictly' last year after his awful dancing ensured he finished at the bottom of the show's leaderboard each week, but was deemed so entertaining by the public, they kept voting to keep him on the show.
