According to In Touch, Angelina Jolie‘s former bodyguard, Mickey Brett, is planning to write a tell-all book that will reveal intimate details about her life. “He knows everything about Angelina. It’s going to be one of the most explosive books ever written,” says a publishing insider. Brett headed up Brad Pitt and Jolie’s security team in Namibia during the birth of their daughter Shiloh. He’ll reportedly also clarify whether or not the couple began their relationship while Pitt was still married to Jennifer Aniston. Jolie is reportedly seeking legal advice on whether she can have publication of the book blocked, but it seems that Brett was never asked to sign a confidentiality agreement.
