Brad Pitt is furious that his ex-wife Jennifer Aniston is set to reveal intimate details about the end of their marriage in an explosive exposé.

Jennifer Aniston will reportedly pour her heart out and bare details of her charmed but troubled life.

Among the many bombshells Jen plans to drop — in a deal publishing industry insiders say could be worth up to $6million in advances alone — are:

Exactly how ex-husband Brad Pitt told her it was over between them.
Just how faithful Brad was during their five-year marriage.
Her face-to-face encounter with love rival Angelina Jolie.
That Vince Vaughn was a better lover than Brad.

"She feels like Angelina stole her man, her plans to have a baby … and now it feels like she stole her career!" a friend reveals.

A publishing source says Jennifer Aniston's been "inundated" with offers for her candid, hold-nothing-back autobiography.
