Christopher Ciccone, the baby brother that Madonna had a falling out with years ago, has written a shocking and juicy tell-all book about his famous superstar sister which is coming out next month.
Sources tell the New York Post that it's going to ride rough on Madge: "It's extremely graphic and devastating. He wrote it on the sly without telling Madonna."
'Living With My Sister Madonna' will chronicle Christopher's 47-year relationship with the 'Material Girl' singer. It's being published by Simon & Schuster.
Ciccone has been working alongside Wendy Leigh, who has written celeb bios on Liza Minnelli, Grace Kelly and Arnold Schwarzenegger.
This is just so wrong pimping off of your sister like this ... I can't wait to read it! : )
