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."

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.

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**.

Mum loves me being famous! She is so excited and proud, as she had me so young and couldn't support me, so I am living her dream, it's sweeter for both of us. It's her 40th birthday soon and I'm going to buy her 40 presents.

I've never had a problem with the way I look. I'd rather go for lunch with my friends than go to a gym.

I will not do festivals. The thought of an audience that big frightens the life out of me.

I want to leave an album behind that is classic, that people in 50 years will refer to and pass on to their children. An album that you never bored of.
