'It Girl' is such a weird term. It implies I go to parties and drink champagne.

Sometimes it's so weird just to do an interview. This morning I was back in my parents' house, with my brother, and we went for a jog together, then had breakfast as a family. And a couple of hours later I'm wearing high heels and a dress and makeup, and talking about my job.

In London, people can be so... well, it's not even a case of people being unkind or unfriendly. You just don't make any contact in London. You go from A to B with your eyes on the pavement.

I want to drink champagne from ladies' shoes.

Think champagne, drink champagne!

I remember in 'Pride and Prejudice' I had to do a scene where I broke down. And before we filmed I spent like three hours imagining my mum's funeral. Actually, she's very much alive, happy and healthy. It was really horrible.
