X Factor winner Joe McElderry has revealed that he has been advised to start hitting the gym and bulking up his tiny frame.

In a bid to build a legion of young female fans, Joe intends to muscle up and also get his teeth fixed before he releases his debut album.

Joe told Heat magazine: “Cheryl tells me I need to eat more.

“She says I’m too skinny – everyone does.

“I lost weight on the show. You’re working so hard and you can’t put in what you take out. It’s the adrenalin.

“I need to bulk up. And I’d like to get a brace and get my teeth sorted out.”
