Simon Cowell recently confirms that Britney Spears will appear in "The X Factor" to sing her eagerly-anticipated comeback single, "Womanizer". The reality TV show's judge 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," Simon explains in a further statement about his excitement referring to the upcoming show. "And, if she wants to shave her head before she comes on the show, she's welcome to. I don't care."

Previously, the "Piece of Me" singer was reportedly upset over the leak of "Womanizer". Claimed to be half-finished, the song was returned to the mixing room for a final touch and through a spokesperson from Jive /Zomba Records, the tune was then announced to be dropped on September 29. Furthermore, the song will appear in her sixth studio album, "Circus", which is due for release on December 2.
