I really love being in London at weekends - there's always so much to do.

I love getting dressed up. Being a pop star is the most brilliant job for that. A lot of girls love shopping, but they might see the most amazing outfit and think, 'When am I going to wear that?', so it's my duty to exploit the fact I do have events I can wear these things to.

Writing songs about fancying people in dance clubs is all very well but it's not the be-all and end-all. There are other topics.

I tasted huge success with my first album, and when it's happening it feels like a roller coaster you can't get off. You should be very careful about wishing for success on that scale.

Turning the thermostat down is something that I do pretty reluctantly. I like to be able to walk around in whatever I fancy at home.

I'm someone who has always been quite clear about what I like. In the studio, I'm not a control freak but I know what I want.

Not all my shoes are designer. In terms of clothes, everything is on the same level for me. If I like it, it doesn't matter if it cost £200 or £2. I'm attracted to things rather than labels.
