Keira Knightley has hotly denied being anorexic, but she knows the disorder runs in her family. The actress stunned onlookers with her bony frame at the UK premiere of Pirates Of The Caribbean yesterday (04JUL06), but insisted she was healthy. Although she is adamant she has never suffered from the debilitating illness, she has experienced its horrors after watching her grandmother suffer. She says, "People said to me yesterday, 'How does it feel to be anorexic?' "I had no idea that I was. I can safely say that I'm not. "I've got a lot of experience with anorexia. My grandmother and great-grandmother suffered from it. "In a way it's good that it's out there and people are talking about it. "It's quite interesting because it's normally high-achieving women who suffer from it because, I guess, they're control freaks."
