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.

Men are wary of me because they know, by listening to my music, that a relationship with me will be quite deep.

I believe that when you have fans, they invest in you not just as a singer but as a person as well. It's not enough to just have good songs and a good voice.

You never know what to expect. You don't just walk on and expect an amazing reaction.

When I heard Bjork's debut, that was when I first realized that I could be a singer, even with my unusual voice.

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 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.
