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**.

I know you haven't made your mind up yet But I would never do you wrong I've known it from the moment that we met No doubt in my mind where you belong

If I were a writer and not a singer in 10 years, I don't know how I'd feel about writing really personal songs and getting someone else to sing them.

I can't believe I did a peace sign on TV - like Ringo Starr!

There will be no new music until it's good enough and until I'm ready.

I don't want to be on the cover of Playboy or Vogue.

The way I write my songs is that I have to believe what I’m writing about, and that’s why they always end up being so personal - because the kind of artists I like, they convince me, they totally win me over straight away in that thing. Like, “Oh my God, this song is totally about me.”
