Ian Halperin is the writer, who is also an investigative journalist and the number one seller of Unmasked: The Final Years of Michael Jackson.
Brangelina Exposed will answer questions of how the couple has "successfully manipulated the public into believing a glamorous fairytale that bears little resemblance to the reality of the pair's life together," says a press release.
Halperin also speaks about Pitt's marriage to Jennifer Aniston and the "real reason" for their split.
The writer also spills about Jolie's past with "new details of her volatile relationship with and estrangement from her father Jon Voight, her struggles with suicidal impulses, her heroin use, her sexual exploit and her remarkable rise to become an Oscar-winning actress."
Halperin will tell about "the key figure behind the scenes who orchestrated her makeover into a United Nations Goodwill Ambassador."
But the book also points fingers, saying that not all is well.
"Jolie's personal lifestyle choices are not only affecting her growing family," the release says, "but causing serious and potentially irreparable tensions with Pitt."
