I use debit cards for everyday purchases, as I don't believe in credit cards. But this has caused problems, especially with American touring, because I refuse to have a credit card - and in America you can't pay for anything on a debit card.

I was mainly raised by a working mum who didn't have much time or inclination for making food. So I had three or four basic meals: fish fingers and a tomato; a packet scotch egg and a tomato; pasta with a tin of tomatoes; and extra mild plastic-y cheddar chopped into cubes with bits of cucumber.

I wasn't really comfortable reading until I was 12.

I don't know anyone, from any class, who's had a perfectly easy life. I've met people born into wealthy families who feel like they didn't have much emotional support, and people who come from working-class families who had loads of love but no money.

Ever since I was little, my mum used to choose an outfit for me and lay it on the bed so I'd know what I was wearing the next day. I never went to a uniformed school, so I always had an outfit - and I never really grew out of that, I don't think.

Anything that's on television as often as someone on 'The X Factor' is what's successful. That doesn't mean that I condone that or think that it's right. To be honest, I'd be the first to say I think it's a shame. But if that's the way it is then that's the way it is.

I'm under no illusion that there are things about me that I'd like to change. I just accept who I am, and I'm proud of it.
