All of a sudden to get all of this attention, and to be away from home and working all the time was hard. I was on planes all the time. I didn't see my friends. I cried a lot. It was quite terrifying.

I don't get why it would be interesting. I'm not that different. And also, now with Instagram and everything, everyone's so on their phones that even when I'm in a restaurant like this, where you wouldn't expect it, someone will come up and ask to get a picture with me and I'm like, 'No!'

Modeling can be a bit brain damaging. Starting my own brand was what I needed to do. I only model if there are such good jobs that you don't want to say no to. All that dressing up makes me say, 'What do I want to wear?' and, 'What do I want to do with Topshop?' It all kind of leads into the other things.

When you're shooting you go to references in your mind. You think about how you should stand in these particular clothes, or how you should move. You think about the different characters you're playing, really.

I do love New York. But I'm a Londoner at heart.

I always have this fear that one day you are going to discover that I'm not as great as you once thought I was. Nothing feels as good as skinny feels.

Then finally I said, 'Okay, well, I want to know all the details. I want creative input. I want to be consulted. I want to know what they're doing and who's involved. And I want to see the space.' So they took me to see it, and then I realized it was major! All these red flags on the Rue de Rivoli with my name on them right by the Louvre!
