Simon Cowell Confirms Britney Spears Show 9/25/08

Latest: Simon Cowell has confirmed Britney Spears will appear on his British talent show The X-Factor, admitting she's the "number one booking in the world".

Spears will perform on the show to promote her comeback album Circus and the music mogul, who has always been a big fan of the Toxic singer, can't wait.

He says, "We have the number one show in England. It's the best show for her to perform on. We're absolutely thrilled to have her.

"Everyone wants to work with her because she's a star. She's the number one booking in the world at the moment for a show... The fact that she goes a bit crazy occasionally makes her more interesting.

"And, if she wants to shave her head before she comes on the show, she's welcome to. I don't care."
