Earlier in my career I just thought "I'm not very confident, I don't like singing to people." But people had some faith in me, and here we are. Sometimes I think "Oh maybe I should just be a backing singer." But I've got an amazing team of people who tell me to shut up when I'm like "Oh god, I can't do it." But now, I can't really imagine it being the other way.

American fans want to meet you, and they wait for that autograph by the stage door. In the UK, it doesn't really happen that much.

I dress in a sophisticated and classy way - I always dress in a way I know my mother wouldn't be embarrassed to see.

Dance music has pushed its way into the mainstream. Which is good for me.

I always have to pretend I'm somebody else to give the best performance. It kind of feels like I'm acting; it's definitely an exaggerated version of me. I'm a very normal, down-to-earth person, but I wanted the videos to be striking, so I have to lay it on a little bit.

I want to look classy and sophisticated. For the "Running" video, I wanted to make a bit of a statement and to be slightly over-the-top. I'm not taking the piss out of myself, but I'm not taking myself too seriously, either. I'm just having fun and trying to pretend I'm a pop star, really.

If I make a song where I'm happy, I sound completely mad - I think my voice is better-suited for sadder songs.
