* It doesn't matter how big the audience is, as long as they are enjoying it, it's fine

  * Watching Elton John singing my song with Eminem on the Grammys was just bizarre

  * I can't go to Tesco without people following me down the aisles whispering, "That's her". It started off in Marks & Spencer's and now it's every supermarket

  * I'm an all right musician who is rubbish at everything. I used to be a great classical player but I let that slip. Sometimes I play piano live but then I can't sing. It's like rubbing your stomach and head at the same time

  * I go shopping, clean the flat, cook my boyfriend's dinner. It's great selling records, but it doesn't mean you have to turn into a freak

  * I'm not actually putting me out through my lyrics. I'm trying to put feelings out. I'm not sort of saying this is me, because if I was, I'd be a psycho

  * It's much better when I go out with my mates and we stop talking about me like I'm some sort of egomaniac. It's great when we can just have a drink

  * I was going to play for Arsenal, and that was final. I was going to be the first girl in the team. I was disappointed when I realised that wasn't going to happen

  * I'll never as long as I live write a song about what it is to be famous, at that point, remove me from this life, I've lost it

  * My perfect day is going to the pub and then a football match

  * I don't give a flying f*** about any other chart

  * It's so much fun, it's making me giggle. I feel like a princess today

  * I can be really horrible sometimes, a total bitch
