Keira told KP International "I haven't got a clue about how much I weigh. I do not own any scales. And I have noticed it creates an anger in people who are not skinny. People like to blame their insecurities on other people."

Apparently Keira's sel-esteem issues don't detract from her ability to show off her body in almost nothing at all. In her upcoming film "Atonement" Knightley appears almost entirely nude in one scene.
