“The Greatest Thing,” Cher’s duet with Lady GaGa that was never to be released is leaked – give it a listen!

Cher had said in a recent interview or two that she was unhappy that Lady GaGa had nixed inclusion of their duet The Greatest Thing on her Closer to the Truth album due out next month.

But the pop icon is still furious that the song has been leaked online – just days after GaGa’s single Applause was also leaked.

Cher took to Twitter to declare herself ‘disappointed’ and a few more choice words.

‘Ive Sat on fkng song 4 over a yr,’ she raged. ‘NOW SOME ASSHOLE LEAKS WRONG VERSION! GaGa’s SINGLE IS GREAT, & THAT’S ALL THAT MATTERS.’

Further letting off steam, she tweeted: ‘FK.’

Cher tweeted a third f-bomb and wrote: ‘WHY DO PPL THINK THIS KINDA LEAKING SHIT IS OK ! I’m so Fg DISSAPOINTED.’
