Lady GaGa is to team up with Cher for a collaboration.
The veteran pop legend has long been keen to work with the Poker Face hitmaker and was thrilled when Gaga wrote a song for her new album.
Cher previously insisted the track, titled The Greatest Thing, would not be a duet, but she has now revealed Gaga will be joining her in the studio to record vocals for the song.
In a post on, Cher writes, "Can't wait till Gaga puts her voice on The Greatest Thing. She will rock it so f**kng (sic) hard!"
