I would say probably not being able to do what I want to do and not being completely fulfilled and happy. I don't know how that would manifest itself in a mirror. It's just that feeling of not being satisfied with my life would be the worst thing that could ever happen to me.

I have no sense of being famous - you're just working. And then you'll have a random day in London when you'll do some press and it creeps into your awareness that this goes out - that what you do every day goes out to televisions right across the country.

I would like to think I'm a good secret-keeper, when it comes to friends. I'm quite loyal like that.

Being in Doctor Who has been so amazing. I don't think I will ever have a job quite so fun ever again. I feel sad because I am going to leave, but with any story, it has to come to an end.

I don't actually do any exercise, which is really bad. But I wear heels a lot. My theory is that it's painful, so it's gotta do something.

I never cared about modeling. As a model, you're powerless.

All I look for is good quality stuff. Whatever I read, if I like it, then I want to do it. It's as simple as that. I don't have a master plan of, "I should do this genre, and then this."
