I've decided I am going to start loving my backside because I don't know anyone who does that. And for my daughter, I want to be able to say to her, 'I love this.'

When I think about somebody like Keira Knightley, whom I don't particularly know, I see somebody who is working hard, really trying to challenge herself and make smart choices in spite of people criticising her size and performances.

As a young girl, I never felt attractive. I was fat and unhappy at times, and that kind of thinking stays with you your entire life. There's always going to be a part of me that worries about not looking as slim as other actresses. But at a certain point, when you achieve a lot of your goals and you can be proud of your work, you start to relax more about who you are. And that includes your appearance and self-image - I don't think I look too bad for a mother of two. But women shouldn't have to feel the pressure to compare themselves to actresses or models.

God, my brain really goes to mush when I'm pregnant.

I'm a normal human being. I don't have any desire to change my body as a result of having had two kids. That's a good thing, isn't it?

Acting is about being real, being honest.

I'm often moved by the circumstances around some of my characters, but I don't think I've actually cried watching myself.
