The character is everything that I felt really strongly against - she's superficial, materialistic, vain, amoral. She's all of these things, and I realised that I really hated her. How do you play someone that you hate? But I found it really interesting and it gave me a whole new insight into what my job, or my role as an actress, could be.

My friends are all really nice about my fame, they're just curious really, they ask lots of questions.

I would love to persuade Christopher Bailey to get even just a section of Burberry that's, like, organic or free trade. I love him, he's a very good person and an amazing designer, and I have a lot of respect and time for him.

I do things in my own way, but I've never felt any need to rebel. To be honest, I've always had far too much freedom. I had a job when I was 10. I started living on my own when I was 17 or 18. I've earned my own money; I've traveled the world. What would I rebel against?

I don't know anything about American history or presidents. I don't know what tailgating is! I've never been to an Olive Garden!

Dan Radcliffe and Rupert Grint to me are like a pair of warm-hearted brothers.

I like books that aren't just lovely but that have memories in themselves. Just like playing a song, picking up a book again that has memories can take you back to another place or another time.
