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.

I read a comment [about me] on YouTube that I thought would upset me — ‘Test pilot for pies’ — but I’ve always been a size 14-16 and been fine with it. I would only lose weight if it affected my health or sex life, which it doesn’t.

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.”

I'd lose weight if I was an actress and had to play a role where you're supposed to be 40 lbs lighter, but weight has nothing to do with my career. Even when I was signing a contract, most of the industry knew if anyone ever dared say lose weight to me, they wouldn't be working with me.

The focus on my appearance has really surprised me. I've always been a size 14 to 16, I don't care about clothes, I'd rather spend my money on cigarettes and booze.

I don't want to be in everyone's face. I'm a big music fan, and I get really pissed off when it gets like that and I don't want people to get like that with me.

I don't rely on my figure to sell records.
