I've just never been a tracksuit-wearer.

Having a soul, they say, is like taking sadness and turning it into something beautiful.

I try to maintain a healthy dose of daydreaming, to remain sane.

I'm a light sleeper. I've never been one of those people who can put their head down and suddenly everything disappears. Nighttime is the time I get most scared, anxious or worried. In those darker moments before waking or sleeping is when I feel most, I don't know, I can turn on myself, and my imagination can take me dark places.

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.

I love Lady Gaga and I love Katy Perry and R&B and rap music... I love big, American pop music.

I've been having this really weird anxiety dream about arriving too late or too early, and the people in charge are like, 'You have to leave! You have to go back to the hotel and get ready!' And I use the wrong exit, and I'm running down the red carpet in ­pyjamas, like, 'No! Don't look at me!'
