You get to a certain age and you can't judge yourself on your dad or your parents.

I was super brainy and a proper geek at school, but there would always be a boy. But that sort of obsession did turn me into a songwriter. My writing has always come from that feeling of infatuation.

I'd like to look like Madonna when I'm her age. I also look at athletes and love their bodies. I've always wanted to be muscly, not skinny. A lot of women yo-yo around, but I'm always aware if I'm getting a bit out of shape. I never look at the scales but I can just tell. It goes on my tum and bum.

I don't think there was ever a moment when I was like, 'Yeah, I want to be a singer!' I guess it just happened. I performed a lot when I was younger and stuff, but I remember getting to the point where I thought I might have to get a normal job.

I like the idea about somewhere there being a world... somewhere there's a world that I don't know about. But also, that somewhere, there was once something that disappeared.

It's usually a big kind of vent of frustration or anger or sadness that puts me in the right frame of mind to write. It's such a cliche to say that artists write when they're down, but it's true for me. It's a relief to get out what's eating away at my heart or my soul or my head.

I want to be more like Pixie Lott. She works really hard but always manages to keep smiling. She never complains.
