Billy Joel is reportedly furious. The music icon has publicly slammed an upcoming biopic based on his life, stating it 'doesn't have my approval.' TMZ reports Joel called the project 'misguided,' leaving fans to wonder what details the film might reveal that he's so keen to keep under wraps. This bombshell comes as production was reportedly moving forward without his input. The 74-year-old legend is known for his candid lyrics, but clearly, he draws a line at unauthorized screen adaptations.
