Singer/actress star Kelly Osbourne has vowed she’ll never fall victim to an eating disorder - because she was traumatized after witnessing her mother Sharon Osbourne’s struggle with bulimia.

The 23-year-old lost a considerable amount of weight during her seven-week stint in London musical Chicago last year (07), but accepts she’ll always have a curvaceous figure.

And she insists her mother’s lifelong battle with her body image has scared her away from any unhealthy dieting habits.

She says, "I think watching my mother being bulimic made me never, ever, ever, ever want to have an eating disorder.

"I don’t diet and I didn’t even realize I had lost weight until a dress literally fell off me."
