According to the website Contactmusic, Knightley, 22, was mad at accusations that she suffers from anorexia.
At the beginning of 2007, the star of the Pirates of the Caribbean films was looking thinner than ever, prompting rumuors that the starlet was suffering from an eating disorder.
Knightley explained, "I was completely devastated. I was thinner because of the work I do. The actress admits she even tried to put on weight to stop remarks."
