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.

Being a chef would be too much hard work.

Come rain or shine I walk short distances rather than taking my car.

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.

I've got a thing for footwear; I have about 200 pairs of shoes from all over the world.

I try not to wear anything I have to fidget with - there's nothing worse than wearing something and pulling down the hem and re-adjusting the top. My pet hate is when girls wear those strapless dresses and spend the whole night yanking them up.

The NHS is a bit iffy when you sprain an ankle, but when it's a high-priority issue, it's fantastic. They don't mess about. They're incredibly efficient when things go wrong.
