Superstar Cher has updated her fans on the progress of 'The Greatest Thing'.
It seems we are one step closer to hearing Cher and Lady Gaga's new duet, 'The Greatest Thing'. Cher told her Twitter followers that producer RedOne is mixing the track. The 'Living Proof' singer tweeted;
"RedOne has both of our vocals and is doing the mix now! I haven't heard GaGa's vocal, but I can't wait!"
RedOne is most notable for his work with Lady Gaga; he has co-written and produced several of her biggest hits, including 'Just Dance', 'Poker Face', 'Bad Romance' and 'Judas'.
