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.

My fancy dress costume of choice is... something 1920s or 30s, when there was still so much elegance and attention to detail. An excuse for ultimate dressing-up indulgence.

I tend to write things and review it afterwards and realise what comes out. I very rarely ever write something and have to take it back.

I think that one day I won't have any kind of... sort of, or it will be either way, I won't have to think about anything. But at the moment, god I think probably because of what I do and the nature of how it is, I'm all over the place all of the time.

Because I've always been a runner I love to feel that my body is shining on the inside. I wear baggy clothes, so it's not as though I like showing it off. I just like to know I'm great on the inside.

When I'm writing obviously I have all the nostalgia in the world, I have all the emotion in the world, but then when I actually perform, I need to just perform it, and that's it. I do retain like a little bit of it because I have to, I sing and perform the songs so I have to - it's a performance of the songs - but I just have to get the right balance.

I wrote 'Lights' a long, long time ago. And I expected it to be on the album, because it was - I wrote it with 'Biff' Stannard. And he wrote every single Spice Girls song and every single pop song of the 90s, basically. So I thought, you know, I was really lucky to work with him, but I didn't think it would be a big song for some reason.
