"That's not Cher, she's dead. It's a drag queen."
It is with great sadness that I'm pretty sure that her has been dead since the 70's. but to keep her image "alive", Cher devised a plan to train young aspiring drag queens to take over her image. She took them in, trained them in the ways of "Cher". Only rule, you only get five years and then the next "Cher" comes out. This explains why she always looks a little younger, sounds a touch different, and has all those farewell tours!share
