I got a job as soon as I could - 11 or 12. I started babysitting and then I got a part-time job at a pharmacy in England. I just remember loving the feeling of going out and buying my own clothes! I'd go bargain-hunting and get secondhand vintage stuff.

I wanted to write about relationships. But I didn't feel I had the experience to sing about them in a deep way. Studying psychology helped me out in terms of my understanding. I still look through my old textbooks when I'm in need of inspiration.

People don't listen to one radio station. On iTunes you can mix different worlds and bring country and pop and folk and live music together with a mass audience. I could have sung 'Easy' in a country way but I just sang it how I sing. I think it's a really nice blend.

I'm very honest in my music and I'm often asked to explain the lyrics; as an introvert, I find that quite hard. And I always wear high heels on stage, which can be painful.
