I've learned not to let it be the end of the world if a boy doesn't like you. I used to put so much effort into boys. I started playing guitar because I wanted to impress this boy. Then, I ended up in love with guitar and I didn't care about the boy anymore.

I would like to be mates with Richard Branson because I've hung out with him and he is just the loveliest person and obviously a very rich guy and has a lot of stuff going on, but he's actually a really, really sound person, and he's really positive and he's got a really good energy, so I'd like to hang out with him a bit more.

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.

The nature of how we are as human beings is that we're much more interested in being critical rather than praising something.

Even when I'm in quite a happy state of mind, I like writing really sad songs. I think a lot of people do.

I suffer panic attacks which has made me really conscious about my fitness and I have become addicted to jogging. It might sound odd but a lot of good has come out of it. My fans send letters saying they have taken up jogging because I do it.

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.
