Britney Spears has refused to record a duo with her ex-boyfriend Justin Timberlake. The singer mysteriously cancelled the recording, which was supposed to be produced by Timbaland. A souce told the New York Post, "Timbaland set aside a week out of his crazy schedule to do this - and then, just before she was supposed to fly out, Britney abruptly cancelled the session and refused to do the song. It's crazy. She's looking for a comeback, and this would have not only been a huge hit, but something she could have opened the MTV Video Awards with it and really blown everyone away." |
