With just days to go until Gary Barlow steps out as an X Factor judge, the 40-year-old singer has revealed that he's been working out ahead of his debut. Going in front of around 20 million viewers is a daunting task, and despite being one of the hottest men in pop already Gary still feels the need to shed a few pounds!

The Take That star is expected to be joined by N-Dubz star Tulisa and US singer Kelly Rowland on the show, when auditions kick off on Wednesday in Birmingham. Louis Walsh will return to the panel to complete the line up.

Chatting before his big debut, Gary told The Mirror's Clemmie Moodie: "I’ve lost a stone and 2lbs and feel fantastic."

He added: "I’ve been working out with my trainer, Graham, and just trying to look after myself a bit more."
