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'd hate it to become style over substance, I'd hate people to start putting me in a magazine article about my style. I don't like dressing up in something I'm not necessarily comfortable in just to make it more of a show. I want the power to come from what I sing about and how I sing.

I played recorder in assembly, then I became passionate about the guitar, I don't know why. I started on electric then moved to acoustic - my brother was playing bass in the next room.

If a hundred people want autographs, sometimes you have to say no because you've got to get up for a 4 A.M. flight or something. In that sense, it really pisses me off when people think you've become a diva. It's not becoming a diva, it's because of the situation, I think.

I guess I'm just quite observant and I pay attention to a lot of things. Human behavior really fascinates me.

I feel more confident if my makeup looks good.

I started getting these attacks in 2009, just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist, who told me I needed to make peace with my panic attacks.
