The release of Britney Spears' comeback single 'Womanizer' has been delayed, apparently because the label felt it wasn't good enough and needed a bit more work. And unfinished version of the track was leaked earlier in the week when footage of Spears rehearsing in an LA studio was posted on YouTube, and the fans' reaction wasn't super, which is seemingly why the label decided it required some changes. The song was supposed to air for the first time on US radio on Monday, but didn't. A source says: "The label held the song back to make it as great as possible".
'Womanizer' is due to be released in the UK on 24 Nov, preceding the release of the Spears' sixth studio album 'Circus' by one week. Meanwhile, Simon Cowell has almost-confirmed previously reported rumours that she is to perform the new track on 'The X-Factor', saying: "Yes, I think Britney Spears is going to perform. We're absolutely thrilled to have her. She's a hugely talented person. Everyone wants to work with her because she's a star. The fact that she goes a bit crazy occasionally makes her more interesting. If she wants to shave her head before she comes on the show, she's welcome to. I don't care".
