BRITNEY SPEARS and boyfriend JUSTIN TIMBERLAKE have recorded a “slick” duet together, it has been reported.

Rumours have been circulating about the chances of Spears and her *NSYNC boyfriend recording a duet for a number of months.

Now, speaking to MTV news in the US, Rich Travali, who is mixing the as-yet-untitled track, claimed the song may feature on the teenage sensation’s new album, due for release in November.

Speaking about the song, he said: “It’s a slick pop thing, very aggressive. It sounds really hot.”

The pair are said to have written the track with choreographer Wade Robson, who produced the song.

A UK spokesperson for Spears was unable to confirm the collaboration, claiming the pair had talked about recording together, but was unaware of any recording sessions having already taken place.
