I find it quite difficult to think that there's, you know, about 20 million people listening to my album that I wrote very selfishly to get over a breakup. I didn't write it being that it's going to be a hit.
I doubt I'll be singing forever, because at some point people aren't going to want to hear my music, and I hope that I'll still get the opportunity to write songs.
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.
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.
It's never been an issue for me - I don't want to go on a diet, I don't want to eat a Caesar salad with no dressing, why would I do that? I ain't got time for this, just be happy and don't be stupid. If I've got a boyfriend and he loves my body then I'm not worried.
