Just in time for the holidays, best-selling author Ian Halperin is set to unleash a bombshell book about Brad Pitt and Angelina Jolie, aka Brangelina, giving a behind-the-scenes glimpse as to what the Hollywood supercouple is really like as opposed to how they are portrayed. 'Brangelina Exposed' is set to hit stores on Dec. 1, but is available for pre-order, just in case you're doing some early holiday shopping.
