I instinctively dress a bit tougher because I've spent a lot of time in the U.S. and I realised there was a certain image projected of me here. I've always been an absolute rebel. When I was in my teen years I had piercings and wore all black.

'I Know You Care' is about my dad. And I haven't seen him for a long, long time. And my parents divorced when I was really young. And I guess I just wanted a - it was my way of saying that I wasn't bitter or angry anymore. I was just sad and just felt like something was missing.

There are so many things to think about when you make an album. Like, who am I trying to impress? Am I going to get respect, critical acclaim? Or am I going to sell lots of records?

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'm really proud of 'Bright Lights' because I was still in the mind frame of my first album when I was putting it together, but next time I want to display something different. I don't want to be as young, immature and all about boys!

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

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.
