A new explosive book entitled Brangelina: The Untold Story of Brad Pitt and Angelina Jolie, by Ian Halperin, may give us more info about the power couple than we ever needed to know.

Just yesterday, Us Weekly reported shocking details found inside the pages of the book about the couple, saying "they've broken up so many times it would make your head spin."

Halperin also claims Angelina Jolie "has a temper like a cobra." And perhaps that explains today’s headline, that claims Angelina launched "a mean-spirited but effective campaign" against Jennifer Aniston when Brad Pitt divorced her to be with Jolie.

Halperin says in the book that book that Angelina, with the help of her manager Geyer Kosinski and brother James Haven, planted press stories in 2005 that painted Aniston in a negative light. They said things like Jen put her career before having kids, which was the reason for her divorce.

Whether you believe the things written in the book or not, it sounds like a juicy read!
