Diets are a fool’s errand. I eat something sweet every day, whether it’s chocolate or a cookie. If I don’t, I guarantee you that there’s going to be a day every week when I’m going to stuff myself, especially if it’s PMS time.

I would love to pretend I don't diet, but I work very hard. I stay active and eat very healthy. Anybody who says otherwise is either unhealthy or lying! I will admit that I'm addicted to sugar - licorice, Jujubees and jelly candies. And I actually love bran muffins!

That is the greatest source of my anxiety on this film [The Hobbit], is that I'm going to be lynched.

That's what happens in Hollywood. People are like, 'I want to hate you, because everyone else seems to love you.' But the reality is this: I'm a simple person who's not interested in attention and who just wants to go about her business.

I got called and was told, "We'd like you to do The Hobbit", which was my favorite of all of them when I was a kid - "And we want you to play a character that's not in the books", I gulped and hesitated, but then I went, "These guys know this world, and they represent this world so well, that I actually think they've earned the right to have a little play."

Truthfully, I love being in the jungle. I love it when the make-up artists come to set, they come equipped with dirt and sweat. I spend my days climbing trees and I can crawl out of bed and walk on set and that's exactly all I have to look like.

I think men don't know what they want, so the idea of not knowing what they're getting makes it a little easier on them.
