You both make good points. And yeah she does try too hard it seems. I've also noticed at the UK premiere, she couldn't seem to get her hands off her hips and had to pose that way in every single snapshot save for the ones where she was hanging off Orlando Bloom.
On another note, I think she's annoyed with the anorexia rumors. I saw the interview where they asked her about it and she was really snippy close to the end of her speech. I don't blame her, if someone asked if I were suffering from a fat disorder I would get pissed too. But it's the life. She'll deal with a lot of the hating.
