Britney Spears will perform on The X Factor.

"I think Britney Spears is going to perform," Simon Cowell said.

"We didn't GET her," Cowell said when asked how he managed to get the superstar. "She's got a record coming out. 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," he raved. "I've always said this about Britney -- that she's a hugely talented person. 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 now she has her career back on track -- fantastic. I'm thrilled.

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