Simon Cowell is allergic to wool.

The 48-year-old music mogul explained his aversion to lambs' wool means he has to spend a fortune stocking up on the very best cashmere jumpers.

Simon Cowell hasn't eaten a cookie since he turned 40. The 48-year-old music mogul has had to sacrifice his favorite calorific treats in order to stay in shape since his metabolism started slowing down.

Speaking at the London book launch of 'Michael Winner's Fat Pig Diet' on Wednesday night, Simon said: "Once you get to 40, you really have to be careful about what you eat. Cookies, cakes and chocolate are definitely off the menu."

Simon Cowell is furious with Take That for instigating a chart battle with his protege Leona Lewis. The music mogul, who signed Leona to his Syco Music record label after she won U.K. reality TV show 'The X Factor' last year, has warned Take That they will regret going up against Leona in the U.K. singles charts this month.

Leona's 80s inspired 'Bleeding Love' is released on October 29 - although it is available to download from October 20 - the same day as Take That's 'Rule the World', the theme song to new movie 'Stardust.'
