It's good to talk sometimes. Sometimes interviews are really good for you... You end up evaluating yourself more and talk about stuff that an ordinary person wouldn't necessarily keep revisiting. I used to close myself off and want to be alone, but now I'll call a friend. When you're in a relationship, they're that person.

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.

I don't really have a style icon but I really admire the way people dress like Gaga, Rihanna and Gwen Stefani. It's good to be inspired by singers who write music and dress incredibly - rather than models and people in the fashion industry who dress immaculately anyway because it's their style.

I love prints of skulls and bones and have some taxidermy - a crow and a rabbit - to remind me of home. I like art and have a big portrait of Bjork.

My mum was too busy raising four of us to encourage my hopes. But I'm glad I had the upbringing I did. It made me a worrier and a thoughtful, curious person.

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

The only really safe thing to do is to write a diary of where you've been, what time you went to bed, what you ate. If I wrote honestly about everything I think it'd be a disaster. It would cause a lot of trouble.
