Weight doesn't matter as long as you're happy with yourself.

There's not enough money in the world to get me singing 'Because We Want To' again. I wouldn't do it. I think Beyonce Knowles got a couple of million for a private show but I would be happy to turn it down.

The whole size zero debate is disgusting. My sister, who's 13, looks amazing - but she's already worried about her figure.

In the next few years I'd love to play a female version of Doctor Who. I know exactly how I would play her - she would be crafty in a clever kind of way.

I am thinking about those things now. More so than all my friends - they're a lot older than me, but they're not even thinking about babies.

I now know how to walk around properly in my undies. People would keep telling me to push my tits out! I also now know how to use a whip on people without causing bruising.

People need help, advice and love, not websites telling you how to lose your last pound, or scantily clad, deeply anorexic celebrities parading around flaunting their golden bones.
