I was about to meet Beyonce, and I had a full-blown anxiety attack. Then she popped in looking gorgeous, and said, "You're amazing! When I listen to you I feel like I'm listening to God."

When it comes to staying myself - my career isn't my life, it doesn't come home with me. So it's a piece of piss staying grounded and not being changed by it. The same things I've always liked still satisfy me. My team's the same and my group of friends are the same. Of course I'm bowled over by people's response to 21, and when I meet artists I love, it blows my mind. But it baffles me as well. I go home and my best friend laughs at me, rather than going to a celebrity-studded party to rub shoulders with people who know me but who I don't know. I'm Z-list when it comes to that sh**.

Americans are always mortified when I tell them this, but in England, it's a tradition to put your plaques and photographs and awards and gold records and stuff in your bathroom. I don't know why.

I don't make music for eyes. I make music for ears.

I've been singing properly every day since I was about fifteen or sixteen, and I have never had any problems with my voice, ever. I've had a sore throat here and there, had a cold and sung through it, but that day it just went while I was onstage in Paris during a radio show. It was literally like someone had pulled a curtain over it.

I am quite loud and bolshie. I'm a big personality. I walk into a room, big and tall and loud.
