Where's my heart at? Aw. Um, in my chest. I think it's in there - on the right hand side. Sometimes it's in my mouth and sometimes I can feel it in my stomach, when I get really nervous. So it's pretty physical.

When I'm singing I'm always trying to get to the highest point possible. I'd fly to the top of Buckingham Palace to sing to the queen.

I'm down to bleach my eyebrows again. I tell you what, though - that didn't go down well with my boyfriend. Girls love it. Guys, not so into it.

There's such an extreme feeling to be in love, especially in quite an emotionally destructive relationship, where you're both kind of really bad for each other, but you love each other so much. Those extreme emotions, I think, can only be described with extreme imagery.

I got to live out my 11-year-old fantasies - I got to go on stage with Green Day. Billie Joe called my name from the stage. 'Dookie' was the first album I ever bought. I covered the whole of 'Nimrod' and he'd heard it. That was like the 11-year-old girl dreamed.

I didn't want to become a personality, I wanted to be a musician, but because I didn't have an album to stand by yet it was hard for people to see that. But now, two albums in, I'm happy with things.

'Dog Days' was recorded with pens and the wall, and half a stolen drum kit that was out of tune, in what was basically a cupboard. The only instrument I could really play was my voice, so we just layered everything a hundred times. It was enthusiasm over skill.
