Britney Spears backed out at the last minute from recording a duet with her ex-boyfriend Justin Timberlake, the New York Post reports.
The Post's Page Six gossip column says hit producer Timbaland was scheduled to record the track.
Spears' record label Jive is said to be furious over her decision, which was expected to kick-start a career comeback.
A music industry source told Page Six that Timberlake wrote the duet specifically for Spears. Although the pair wouldn't have been together in the studio, his voice would have been mixed with hers later.
"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," the insider added. "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 and really blown everyone away."
