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.

It's usually a big kind of vent of frustration or anger or sadness that puts me in the right frame of mind to write. It's such a cliche to say that artists write when they're down, but it's true for me. It's a relief to get out what's eating away at my heart or my soul or my head.

I instinctively dress a bit tougher because I've spent a lot of time in the U.S. and I realised there was a certain image projected of me here. I've always been an absolute rebel. When I was in my teen years I had piercings and wore all black.

I record stuff all the time, like little vocal things. I write random things down... Sometimes I just get things stuck in my head and I record them, and that actually becomes a song quite a lot of the time.

I used to be obsessed with Pearl Jam, but I love having pink hair and kind of looking like a Barbie.

I started getting these attacks in 2009, just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist, who told me I needed to make peace with my panic attacks.

I kind of just want to get to know people and I have a genuine interest in people that listen to my music. I've just always felt like that. I think it's from the days of playing guitar to a few people and being very conversational and very intimate and I've always wanted to keep that vibe.
