At least one person is unhappy about the upcoming Madonna biopic "Blonde Ambition" -- and that person is the legendary entertainer herself.

After news broke Monday that the unauthorized project was in the works, Madonna voiced her opinion in an Instagram post. Her comments came Tuesday and made it clear she doesn't like the idea of having someone else tell her story.

"Nobody knows what I know and what I have seen," she wrote. "Only I can tell my story. Anyone else who tries is a charlatan and a fool. Looking for instant gratification without doing the work. This is a disease in our society."

The Universal project is set to explore the early years of her career as she tried to get her first album released. Whether or not her reaction will have any impact on the film remains to be seen. Who knows -- maybe she'll be inspired to tell her own story. We'd definitely love to hear it!
