The 22-year-old British singer, who is famed for her fuller figure, said that although she admires the svelte pop stars on the scene, she doesn't want to look like them.
She told Rolling Stone magazine, 'My life is full of drama and I won't have time to worry about something as petty as what I look like.
'I don't like going to the gym. I like eating fine foods and drinking nice wine. Even if I had a really good figure, I don't think I'd get my t*ts and ass out for no-one.'
She continued, 'I love seeing Katy Perry's boobs and bum. Love it. But that's not what my music is about. I don't make music for eyes. I make music for ears.'
