The 26-year-old singer - whose real name is Louisa Rose Allen - admits some of her supporters have gone to extremes to impress her, even when she didn't want them to.

She said: "I was in Scotland once and a guy pulled his tooth out with pliers.

"He was like, 'Do you dare me to pull my tooth out?' and I was like, 'No, don't do it.' He said, 'I'm gonna do it.'

"He pulled his tooth out and got me to sign it."

Foxes will release her second album, 'All I Need', this month and admits it would likely have been finished earlier if she hadn't been asked to tour with Pharrell Williams.

She told NME magazine: "I was in the middle of writing it and I got a call.

"You don't really say no.

"Most of it got written when I was on tour."

And the 'Body Talk' singer was very impressed by Pharrell.

She said: "I was impressed because he was constantly making beats.

"Two seconds before he'd go on, he's be writing music. He doesn't stop."
