I'm quite private. And I never wanted to be the biggest star in the world really. So in that sense I've got a good balance of doing great shows, of making an appearance every now and then and writing music, and I don't really have to do much else.

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.

Every day I'd say I look different. Sometimes I look really formal, sometimes I love the classic Stella McCartney, Chloe Sevigny and Gwyneth Paltrow thing. Other days I like being rock star and wearing leather jackets and studs. I love wearing Burberry - it's the perfect combination of formal and punky.

After shows my face feels dirty with makeup and sweat, especially in the smaller venues, so it feels good to get back to the bus and smooth it away. Sometimes you need something alcohol-based, especially on tour when you don't always get a chance to keep washing your face all the time.

My hairdresser in the U.K., Adam Reed, has his own line, Percy and Reed, and it's really good. And I use Moroccan Oil and Kerastase as well.

You should constantly write because your writing is always evolving and progressing. It's really important to start writing young.
