Brad Pitt and Angelina Jolie have been through a lot together, from a love affair that began when Brad was still married to their travels around the globe with their six kids. Along the way, one man was by their side: trusted bodyguard and confidant Mickey Brett, who protected Brad, Angelina and their children for years. Now, according to reports, Brett's considering committing the ultimate betrayal. On April 26, New York's Daily News reported receiving a proposal for a tell-all book and TV show based on Brett's work as a bodyguard to the stars. "The main focus of the pitches," the newspaper said, "was Brangelina."

Brett, who was fired in 2008, clearly would have lots to write about. A report earlier this year said he planned to include details of how Brad, 45, and Angie, 33, first hooked up on the set of Mr. & Mrs. Smith in 2004, just three weeks into filming and long before Brad and Jennifer Aniston divorced.

Angelina -- who first met Brett in 2001 and was especially close to him -- and Brad are both hurt and furious about the potential tell-all. "It's hard to think of a bigger betrayal in Angelina's life than Brett going out and attempting to profit from his time with Angelina and the rest of the family," says an insider close to the actress.
