The not-so-secret naked pasts of 'X Factor' hopefuls Sam Callahan and Joseph Whelan have been revealed.
The pair have previously stripped off for magazine shoots prior to their successful auditions on this year's series of the talent competition.
Sam, who impressed the judges with his renditions of 'You're Beautiful' and 'You Need Me I Don't Need You' last weekend, can be seen wearing nothing but a British flag, which hangs dangerously low, in one saucy shot.
Other pictures uncovered from the cheeky singer's past show him flashing his impressive abs and his bum as he takes a skinny dip.
It turns out that Joseph got his kit off too, posing completely naked for Gay Times magazine after his failed 'X Factor' bid last year.
He recently bared his chest to celebrate reaching Bootcamp this year, so we can only imagine what he will do if he reaches the live shows.
Meanwhile, it has been revealed that Sam has had a shot at popstardom before, touring with 'X Factor' 2012 finalists Union J and District 3 earlier this year.
According to the Daily Star, he was also signed to Simon Fuller's label and put in a boyband by Geri Halliwell, before quitting to release a solo single this summer, with the help of the mastermind behind Busted and McFly.
