Madonna could be facing some brotherly betrayal -- Christopher Ciccone, who had a falling out with the pop star years ago, is going to release a tell-all book on his infamous sister. Christopher has teamed up with British journalist Wendy Leigh, and insiders say the book is going to be "brutal."
"It's extremely graphic and devastating," a source told the New York Post. "He wrote it on the sly without telling Madonna. They want to put it out before the lawyers get hold of it."
A friend of Madonna's told the New York Post, "He was there through the crazy years and has many stories to tell. He's seen it all. Oh, my."
The book is due next month and has a massive print run of 350,000 copies.
