It's almost too much diva for one song! Lady Gaga and Cher, both of whom are icons of the highest order in the LGBT community, will duet on the song 'The Greatest Thing,' which Gaga and producer RedOne offered up to Cher to record.

Gaga and Cher, together on one song? Forget Sonny and Cher. It's now Gaga and Cher, forever linked in the annals of pop culture and pop music. Once it happens, of course.

Cher tweeted her excitement about the collab, posting: "Can't wait till GaGa puts her Voice on "The Greatest Thing" SHE WILL ROCK IT SO FKNG HARD!"

Something tells us Gaga won't be the only one rocking it really hard! Cher has a massive set of pipes, and her and Gaga trading notes might be enough to cause sparks to shoot out of the studio wall and to cause the soundboard to spontaneously combust!

We haven't heard a note of music and we are already going to predict that 'The Greatest Thing' will go on to become one of the biggest, baddest, best, and most beloved anthems of all time within the LGBT community. And we haven't even begun to think about the video! It's going to be a spectacle of high heels and even higher hair, with lots of makeup, wigs and haute couture. How could it not be?

In case you are more of a little monster and Gaga devotee and don't know that much about Cher, well, we'll provide a little education to get you up to speed about this OG diva via her video for 'Believe,' which was a massive, late career hit. Check out Cher's headgear and her outfits. You can see where Gaga has gleaned some inspiration for her stage attire!

Gaga and Cher are going to bring it.
