Speaking to an online retailer, the former X factor judge revealed:
'I don’t follow any strict diets, I just eat sensibly.
'I’m not eating McDonalds or pizza every day but I do allow myself one cheat day a week, normally on a Sunday.
'I have a really sweet tooth and love cupcakes, doughnuts. Basically anything that’s really bad for you.'
The songstress and talented dancer admits that she uses a home DVD by celebrity trainer Tracy Anderson to stay in shape.
However modest Chezza cannot quite accept her status as a beauty icon, revealing:
'I still don’t get why people call me a beauty icon. It’s so flattering, don’t get me wrong, but I just don’t get it.'
And her beauty routine is not much more strenuous than her diet.
Explaining that Marilyn Monroe is her idol, she added that a full face of make-up on her day off would be her 'worst nightmare', remembering mum Joan's beauty advice:
'Work with your natural beauty and don’t try something just because it works on someone else, go for what works for you.'
That’s easy to say when you're Cheryl!
