Britney Spears and former love Justin Timberlake will not be making beautiful music together any time soon, according to camp Trousersnake.

Britney is currently recording the follow-up to her 2007's Blackout, and her new record was reportedly set to feature a duet with the SexyBack singer.

But Justin's spokesman has denied a collaboration, insisting he "is not scheduled to be in the recording studio with Britney".

The ex-Mouseketeers split in 2002 after four years together.

Perhaps Justin had reservations about harmonising with this?
