She said: "I don't like the way that suddenly now everyone likes me because I've lost two stone. Why was I a bitch before? Because I was fat?"

The singer claimed that overweight people are vilified more than "a junkie".

Kelly, 23, told Heat magazine: "I was always the fat spoilt brat because I was fat. Just because I'm a size 8-10 now doesn't mean a size 12 was fat."

But she admitted publicity shots for her role in the West End musical Chicago last year were airbrushed.

Kelly said: "They did it for my chin because I had a little bit of a double chin and under my arm because my corset was pulling in so tight."
