Singer and former X Factor judge Cheryl Cole has admitted that the diets of the Girls Aloud members have changed drastically over the years, but they still enjoy treating themselves now and again.

In a new interview with Britain's Glamour magazine, the 'Call My Name' sensation explained that when the popular group first formed they often picked up convenience foods, but will now opt for something healthier like sushi:

"Our diets have gone from one extreme to the other. It used to be Greggs pasties, now it's raw fish. One week I might have a few nights in, eating pizza and watching the X Factor now that I’m not on it."

Cole also spoke frankly about criticism and abuse she has received over her weight and stressed that it's just "bullying in the workplace", which is completely unacceptable:

"You can't call someone who's a size six fat. An average woman is a size ten to 12, so if you're calling me fat because I'm a size six, and I have never ever been bigger than an eight, you're causing women some serious issues."

"When you're on the receiving end of it, it's nothing short of bullying in the workplace."
