A career in entertainment has a lifespan, like one in sport.

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.

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.

Someone had my number and they started text-stalking me. I've never replied to them. It was tempting to write back, but I resisted.

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 do find it a bit disconcerting when your name becomes a brand.

I'm happy that I have a look, but I don't over-analyse whether or not it's beautiful or ugly.
