Could there have been a more GLBTA-friendly duet in existence other than Lady Gaga and Elton John performing at their double-piano at The Grammys? Turns out, yes, possibly – it looks like Gaga will be adding her vocals on the song she and RedOne gave to Cher for her new album. “Can’t wait till GaGa puts her Voice on ” The Greatest Thing,” Cher tweeted yesterday. “SHE WILL ROCK IT SO FKNG HARD.” That we have no doubt. Are you excited about this collaboration, little monsters? And how about you, whatever nickname Cher’s fans are called?
