Cone bras, songs about virgins, dating a wrinkly Warren Beatty—Madonna has made a career out of shocking her fans. One has to wonder if there's anything about the material girl they don't already know. A new biography written by Madonna's brother, Christopher Ciccone, aims to answer the question.

Focusing on Madonna's younger days, the memoir is set to hit book shelves in mid-July. News of the upcoming book, entitled "Life With My Sister," sparked an avalanche of speculative articles in Buzz. What sort of dirt will the book reveal? Is Madonna trying to keep it under wraps? Does she even care?

According to the New York Post, Madge should care because the book is "extremely graphic and devastating." Could the memoir be more painful than her performance in "Body of Evidence"? It doesn't seem possible, but then again this is Madonna we're talking about—expect the unexpected.
