I used to be obsessed with Pearl Jam, but I love having pink hair and kind of looking like a Barbie.

I feel like my figure is a challenge because I'm quite flat chested but I've got a booty so I've got to look for the right things.

Fame doesn't make it hard to date, because I could be seeing someone now and no-one would know. But if you go out with someone who's in the public eye you're asking for trouble. It's double intensity, double scrutiny. Even if I just went on one date with a normal guy, word gets around and that freaks me out. I don't like all that gossipy stuff.

I wrote 'Lights' a long, long time ago. And I expected it to be on the album, because it was - I wrote it with 'Biff' Stannard. And he wrote every single Spice Girls song and every single pop song of the 90s, basically. So I thought, you know, I was really lucky to work with him, but I didn't think it would be a big song for some reason.

When I'm writing obviously I have all the nostalgia in the world, I have all the emotion in the world, but then when I actually perform, I need to just perform it, and that's it. I do retain like a little bit of it because I have to, I sing and perform the songs so I have to - it's a performance of the songs - but I just have to get the right balance.

I feel quite proud to be an ambassador for women who realize that being fit is better than being skinny.

I think hype is a good thing. You need it and it'll teach you valuable things and you'll grow stronger, which is what I've done.
