Lady Gaga & Cher to release collabo The Greatest Thing Ever in September

Is a collaboration between Lady Gaga and Cher the "Greatest Thing Ever"?

That's the title of the song the two gay icons are set to release next month, according to a tweet from the legendary singer.

"The Greatest Thing Ever," a mid-tempo ballad originally written and recorded by Gaga, will be the first single off Cher's upcoming 26th album.

The the divas graced the stage at the MTV Video Music Awards last year when Cher presented the Moon Man trophy to Gaga for her Video of the Year win for "Bad Romance."

"I never thought I'd be asking Cher to hold my meat purse," a tearful Gaga said at the podium before belting out a refrain from her song, "Born This Way."

'The Greatest Thing Ever' was originally written and recorded by Lady Gaga, but now Cher will feature the track on her upcoming album.
