I always liked how people like Grace Jones and Annie Lennox pushed it with the videos. I'm not the most stylish person at all, but there's something about playing dress-up for the day and playing the role of a singer.

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.

I can't eat before I go onstage because I've learnt that burping on stage isn't a good thing. It's all about acid reflux.

I feel like I've got far more gay fans in America... Maybe they caught wind that I have a cute Jewish brother who's gay.

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

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.

I tried a couple of pop writers - none of the big, big, big ones - but it didn't work for me. I do have a commercial voice; I'm not quirky. I'm very normal and that's probably why I like people like Barbra Streisand and Whitney Houston. It's no-nonsense. They sing well, and that's it.
