Bad boy, British pop-rock star Robbie is facing a new challenge. After his drug and alcohol related issues, he is now a 'chocoholic'.

The star is already beginning to worry about his thickening waist line and about the fact that, each morning at the same time (5 AM), he goes into the kitchen and, almost without realizing, eats a bar of chocolate the 'size of Sussex', as Robbie is quoted to have said on a website.

Williams said that he feels comfortable the way he is but when it comes to dressing up and going on a stage he is actually terrified that the others might be staring. The solution is, at this point, rather simple: 'act like you're ace and maybe they won't see the little fatty you saw back in your dressing room'.
