Knightley 'wants to quit acting'

In an interview with Elle magazine the Oscar-nominated actress said she was particularly worried about being featured on pro-anorexia websites.

The star of films like Pirates of the Caribbean and Pride and Prejudice said being famous was "completely crazy".

She added she did not want naturally thin women to be a "scapegoats for promoting a mental illness".

The 22-year-old actress says being the centre of media attention had forced her to reconsider her acting career.

"I think I just have to move away or give it up altogether," she said.

"I couldn't have kids in the situation I'm in now. But I could just do something else.

"That's probably what's going to happen. I'm just not so hungry any more. I made a decision very recently that I wanted a life instead."

Being featured in articles on anorexia had left her "devastated," she admitted.

She said well-known pictures of her in a bikini were taken after a gruelling shoot for Pirates of the Caribbean, where they were filming in soaring temperatures.

"You are wearing a wetsuit underneath a load of corsets. You are fighting with heavy weights in the water.

"Can you imagine a more advanced cardio workout?"
