The story of Lady GaGa, Madonna and other singers.
Not only were the fashions heavily influenced from this movie, but they even look similar in many ways.
But I think that the Lady GaGa stoy is like this movie. She was also playing the music she loved and was molded by a star producer into a persona, someone who sold out some their grassroots music beliefs and fans to gain mainstream stardom.
I'm sure Madonna was the same way.
