I don't think she was contradicting herself because at the time people probably told her it was ok and she wasn't truly aware of the effect it would have on her and the people around her.  Celebrities aren't there to make us question our looks and bodies.  The only reason we think that is because we let them do that to us.  We see a picture of a celeb in a magizine and think "why can't I look like that?"  We are doing this to ourselves.  And its not just celebs that seem to make us question ourselves we see other women around us and think the same thing. Celebs aren't protraying negative influences on purpose we, just make it seem like they are because we are insecure with ourselves.
