I went to Clive Davis' Grammy party and I nearly spontaneously combusted because everyone on my iPod was there! - Leona Lewis

Those women are the true divas. They're amazing performers, whom I've listened to for years. These are the people who've inspired me to sing, so it's flattering that I'm being compared to them. But I have a lot of hard work to do first.

You have to have the courage to stand up for what you believe in – no matter how hard it is – as your beliefs make you who you are amid all the celeb madness. I'm a vegetarian and never wear leather or use products tested on animals. When I was just starting out I'd get a gazillion freebies thrown at me, so it was hard to know what contained what. Now, I've made sure that before I get to a photoshoot people know my stance on that.

[People] would ask me, "what do you want to be when you're older?" and I'd be like, "a singer", and they'd be like, "what do you really want to be?" and I'd be like, "oh, I really want to be a singer."
