I'd hate it to become style over substance, I'd hate people to start putting me in a magazine article about my style. I don't like dressing up in something I'm not necessarily comfortable in just to make it more of a show. I want the power to come from what I sing about and how I sing.

Drake, I'd like to collaborate with. He's a phenomenal lyricist. Probably the best rapper in the world at the moment. I love Kanye but there's something about Drake; he's more straight up, really clever and really poetic and metaphorical - I love that. He's just clever.

My soul is to sell. The dark is too hard to beat 'cause they're calling me.

I was super brainy and a proper geek at school, but there would always be a boy. But that sort of obsession did turn me into a songwriter. My writing has always come from that feeling of infatuation.

I think that one day I won't have any kind of... sort of, or it will be either way, I won't have to think about anything. But at the moment, god I think probably because of what I do and the nature of how it is, I'm all over the place all of the time.

I still love the skinny jeans thing and I wear my favorite leather jacket constantly. I like being kind of a rock star. I love that I can feel comfortable in a small dress or I can feel comfortable wearing a baggy T-shirt.

I met Prince William at a musical festival and he let me know he was a fan of my music. But the invitation to sing at his wedding reception came completely out of the blue. The fact that Kate and William knew the words to my songs was very touching.
