Simon Cowell takes his own beer to restaurants.
The music mogul follows a strict diet after undertaking a food intolerance test and discovering brewer's yeast made him sluggish, and now insists on keeping special yeast-free Sapporo beer in his car at all times.
He said: "I've got a crate of it in the back of the car. Literally."
As well as taking the food test, Simon is becoming more and more health and body conscious.
And the vain star - who has previously confessed to having Botox injections - admits he is paranoid he is going grey.
Speaking about appearing on advertising posters for his talent search shows, which include 'The X Factor' and 'American Idol', said: "Have I got grey hair? If I have they weren't there six months ago. And if I have got grey hair I'm not going to be on any billboards."
