I still don't know if I can write songs. I don't think anyone ever knows if they can write songs.

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.

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.

Fame doesn't make it hard to date, because I could be seeing someone now and no-one would know. But if you go out with someone who's in the public eye you're asking for trouble. It's double intensity, double scrutiny. Even if I just went on one date with a normal guy, word gets around and that freaks me out. I don't like all that gossipy stuff.

After shows my face feels dirty with makeup and sweat, especially in the smaller venues, so it feels good to get back to the bus and smooth it away. Sometimes you need something alcohol-based, especially on tour when you don't always get a chance to keep washing your face all the time.

I could always sing, from a really young age, but my voice was really weird. I used to make my mum turn up the radio every day in our house. She was well into music so I got that from her.

I wrote a lot of poetry that was based on stories of the sea and I was really inspired by that.
