You live and you learn.

Bono told me how to dance in high heels and he also told me about U2's Glastonbury performance and how everything that could have possibly gone wrong went wrong, including him ripping his trousers on stage. I think he was lunging and his trousers ripped! He was telling me how he had to find a new way of performing that didn't involve moving.

On stage, you can use your emotions. It's the place where you can channel them. They have a purpose.

When you're heartbroken, you're at your most creative - you have to channel all your energies into something else to not think about it. Contentment is a creativity killer, but don't worry - I'm very capable of making myself discontented.

In a conversation, the words can get stuck, I don't know what to say, I get very anxious.

I didn't want to become a personality, I wanted to be a musician, but because I didn't have an album to stand by yet it was hard for people to see that. But now, two albums in, I'm happy with things.

When I first started, especially because I got the Critics' Choice before I'd released an album, there was a lot of scrutiny on what my character was, what my background was, what colour my hair was. I fought quite hard for the music to overtake the personality aspect.
