It's so important to take vitamins. People always get ill on tour because of the close proximity in the bus with everyone.

I still don't know if I can write songs. I don't think anyone ever knows if they can write songs.

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.

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.

You pick up loads of baggage with your first record with reaction to it from fans and critics. So I went to Ireland by myself for a couple of weeks with my guitar. I read lots of poetry, I read Patti Smith's autobiography and started words and phrases and then songs started to take shape.

I got approached by SoBe a few months ago about being an ambassador and I learned about the previous ones including Naomi Campbell, so I was instantly interested! Then I tried and really liked it. It's different and has interesting flavours... we don't have anything like it in the U.K.

When I sing along with Britney Spears I will sing in an American accent. But eventually I found my own voice. My songs are so brutally honest, it would be alien to sing in any accent other than my own. Don't get me wrong - I can imitate singers. I can do bar mitzvahs and weddings.
