George Michael will unleash all of the skeltons in his closet in an upcoming autobiography tell-all. The Wham star has signed a multimillion-dollar deal to pen a “no-holds-barred” autobiography, HarperCollins Publishing announced on Wednesday.

Michael’s manager Andy Stephens said: “George has promised HarperCollins a no-holds-barred biography, and it’s certain to be just that.”

“People aren’t stupid, they’re beginning to notice that the truth is more interesting than the stories the press come up with.”

The book, dubbed “one of the hottest remaining untold celebrity memoirs”, will cover the pop star’s personal and professional life and will hit the shelves in Fall 2009.
