Madonna has some strong words for the producers of a planned biopic on her younger years, before she hit the big time.

“Nobody knows what I know and what I have seen,” she said in an Instagram post.

“Only I can tell my story.”

Universal acquired the rights to a script, called "Blond Ambition," about the Material Girl's life in New York and her struggles before her first album, "Madonna," was released, according to the Hollywood Reporter. Brett Ratner is expected to produce the film.

Madonna isn't pleased about someone else telling her story, saying that "anyone else who tries is a charlatan and a fool."

She said the project is an example of “instant gratification” and “disease in our society.”
