I saw 'The Artist.' It's really beautiful and it's all done to the letter with all the silent film techniques. The costumes were amazing and the dog is so good.

I have this sensation of being in flight all the time, but being on stage is like creating a sanctuary in which you can completely lose yourself. The bits of your personality that you keep under wraps in ordinary life, you can let them run free.

Being heartbroken is like having this really horrible freedom. You can be selfish with your thoughts, which can lead to manic creativity, but at the same time you're just really miserable.

The Teenage Cancer Trust does incredible work supporting and caring for teenagers and young adults with cancer, and it's a cause that is really close to me and my family.

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.

You know, people always ask, 'What are you like offstage?' And I always say, 'Well, I'm completely normal and mellow.'

When something really hits me, it makes me want to either jump off something really high or lie down and be buried. I want people to get hit and caught by my music.
