Sometimes you have to be a diva. All the artists I admire from Madonna to Whitney to Mariah have all been called divas. If you are strong, if you have vision, if you are an artist, you have to do what you believe in. And if you get called a diva for it, then so what.

If you don't believe in yourself nobody else will believe in you.

The way I look at it, a footballer wouldn't play in flip-flops or dip their feet in acid and then expect to get to David Beckham's level. My voice is my living, so I'll be looking after it.

I am a very honest person, and I can only say there are moments in my life where I really did think I was being me in the sense of my morals and beliefs and the way I acted. But when I look back at certain things that I wore and my hair and make-up, I was like, 'Whoa! That wasn't me!' But I didn't know it back then.

A hairdresser who did my hair said, "You, my darling, have something that we call successful' hair," which is basically battered hair that's split and falling out in the back because you've had to blow-dry it every day. I don't want my hair falling out, so I wear wigs!

I was obsessed with the Spice Girls! I always wanted to be Sporty. Or Posh, but I wasn't pretty enough.

We're flying free like birds in the sky, because we're ALIVE.
