Some people don't have a way of that catharsis and I do, so I'm lucky in that sense that people listen to my songs and enjoy my songs. It's a really important thing for me, it's how I channel everything. I don't really know what I'd do if I didn't 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.

In Australia and New Zealand, and New Zealand especially, I always find everyone is so nice and friendly. It's one of the few places that I remember visually, like I remember where I stayed and my surroundings - and that's a good sign, because I've got a terrible memory. I'm looking forward to it!

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.

If I've got Writer's Block it generally means that I don't have that much to say or something's not quite connecting. I have had Writer's Block a bunch of times and it's generally because I'm not able to write down what I'm feeling basically. Mostly, I just need to be alone really, or be with someone who can bring that out of me.

Gwen Stefani has amazing style. I used to really love Courtney Love, and anything she wore I loved. Or Chloe Sevigny, because I really love that sort of classic look, and I like being girly and flowery, and wearing little D&G dresses. I wear hats a lot, too. I think it goes back to when I was a bit grungy and was a skater girl for a bit.

Mumford & Sons' music appeals to a lot of America. I'm really proud of them.
