Actress KEIRA KNIGHTLEY was left "completely devastated" after being accused of being anorexic.The Pirates Of The Caribbean beauty was a source of constant speculation earlier this year when she appeared thinner than usual - and admits the media scrutiny has taken its toll. She says, "I was completely devastated. I am thin because that’s what I am and I was thinner at that point because of the work I do. Nothing else." The actress admits she even tried to put on weight to stop the snide remarks, adding, "I asked a doctor what I could do to put on weight. He told me that for someone of my body type to get to a size 12, I would have to eat a lot of s**t food, stop exercising and drink loads…"But I don’t want to have to go around eating crap and being really unhealthy in order for people to stop having a go at me."
