Keira Knightley on Weight

Teeny-tiny “Anna Karenina” star Keira Knightley is snapping back at the body-image pressure in Hollywood.

"I think the pressure we put on women to either be thinner or fatter or to have longer legs or shorter legs or bigger breasts or smaller breasts is disgusting,” Knightley said.

“It's amazing in 2012 that that level of misogyny over women is still there… Particularly over young women. We pull them apart," she said.

Knightley, who has experienced a lot of scrutiny about her itty-bitty frame, says, "I'm a person. I'm completely flawed and nobody should look up to me as a role model. But, hopefully what I can do is make some interesting stories."

Knightley, who is engaged to James Righton, once filed a lawsuit against a magazine that called her “anorexic.”

“The anorexic stuff–it’s always going to have an impact, so I think it did hit pretty hard, because you go, oh, maybe that’s right! I knew I wasn’t anorexic, but maybe my body is somehow not right.”

Her mother insists that her daughter inherited her frame from her tall, skinny father, Will Knightley. Knightley Jr. eats a high-protein diet with lots of carbohydrates to try and keep weight on. Family and friends maintain Knightley eats like a horse, and has to continually eat to keep from losing.

“I've got a lot of experience with anorexia - my grandmother and great-grandmother suffered from it, and I had a lot of friends at school who suffered from it, so I know it's not something to be taken lightly and I don't,” Knightley has said.
