X Factor winner Leon Jackson shows he's a real cheeky chappie behind his shy smile.

The 18-year-old Scot had fellow singers including Hope's Emily Biggs, 17, cracking up with laughter when he pranced around as the Butt Naked Chef in the contestants' house.

And he even persuaded Same Difference's squeaky-clean Sean Smith, 21, to wear just a saucy apron and chef's hat too.

A show insider said: "Leon was the joker of the pack throughout X Factor. He always wanted to make people laugh and that's why he and Sean did the cooking in the buff.

"They expected to get a roasting from bosses but it was all in good taste."

Leon will have a Happy Nude Year if, as expected, he scores his second week at No 1 with his song When You Believe today. That will guarantee him plenty of exposure in 2008.


Our source joked: "People are going to see a lot more of Leon over the next year - and hopefully he'll never hit a bum note."
