I'm never happy with my face, my hair, I haven't really got any boobs and I'm not really that tall.

Well, on tour I eat terribly, so I balance that by running a lot. And then I started to run with my fans in certain cities. It sounds very nerdy and un-rock n' roll, but I like it. It's fun, and it's better than meeting fans in weird, awkward circumstances. So I take them running with me.

Men are wary of me because they know, by listening to my music, that a relationship with me will be quite deep.

Every day I'd say I look different. Sometimes I look really formal, sometimes I love the classic Stella McCartney, Chloe Sevigny and Gwyneth Paltrow thing. Other days I like being rock star and wearing leather jackets and studs. I love wearing Burberry - it's the perfect combination of formal and punky.

I played recorder in assembly, then I became passionate about the guitar, I don't know why. I started on electric then moved to acoustic - my brother was playing bass in the next room.

I never remember having a plan. All I could think about was how I was going to afford to get into college or where I was going to stay because I hated being at home. I didn't really have time to think about anything in the future. I didn't think about a career or anything. I went to uni, got a couple of jobs, so I sort of funded it myself.

The only day I remember of my parents' marriage was the day my dad walked out. As I stood there at five years old, with my older sister and younger brother, I knew that he was gone.
