New Brangelina Biography:explosive details on their relationship, on Angelina’s incest and on why they’ll soon break up

A new biography of Angelina Jolie and Brad Pitt claims the couple’s relationship is so unstable that it will not even last two years.

Celebrity author Ian Halperin is so confident in the assertions in his new book “Brangelina: The Untold Story of Brad Pitt and Angelina Jolie,” that he told PopEater that he would be willing to sleep naked in Times Square should anyone prove him wrong.

Halperin’s coverage runs the gamut from Angelina’s drug issues and depression to incest with her brother, which he claims was swept under the rug with a quickie marriage to Billy Bob Thornton.

Halperin also argues that Brad did cheat on Jen with Angelina, despite claims to the contrary.

“I spoke to people who worked on ‘Mr. & Mrs. Smith’ and they said there [were] fireworks between them from the first day of shooting. I think Angie had a plan to get Brad. She knew he was the most desirable man in Hollywood.”

Halperin’s confidence in the accuracy of his work rests in his access to over 900 sources for the book. He told PopEater, “there’s been so many stories about them, so many rumors and innuendo, and I really feel I was able to get the story behind the story and break it down properly.”

Here’s a few more excerpts of his interview with PopEater:

What was the most shocking thing you took away from your research?

The whole era with the incest allegations and deflecting that. She’s what magicians would call misdirection. That’s what she’s a master of in her camp. She checks herself into a mental institution, and next thing you know she elopes with Billy Bob Thornton and that was a very concerted effort to make sure she was never with James Haven again because Hollywood was ready to blacklist Angie. They just couldn’t accept her open-mouth kissing her brother at the Oscars, and denied or not, she did it at the Golden Globes, several parties. And when Hollywood stepped in, they gave them a stern warning. They said ‘Angie, you’re never going to work again. You better deflect the media’s attention,’ and she did a great job of doing that with Billy Bob.Going back to the Jen Aniston angle of the book and the claims that Angelina Jolie spread rumors saying that Jen couldn’t have children or didn’t want to have children as a way to vilify Jen, how do you think both Jen and Angie handled the situation? Should Jen have come out and addressed it?

It broke Jen down emotionally. They did have a turbulent relationship though. Just yesterday, I was talking to a close friend of Aniston who told me that Aniston would regularly check herself into hotels just to get a bit of separation between them towards the end. But, she was still madly in love with him and wanted to have children with him, so it devastated her. What she did was perhaps the most commendable way I’ve ever seen a Hollywood star deal with such devastation. She was able to keep quiet about it all, get into spiritual counseling and really move forward slowly but surely without sounding like a victim or sour grapes. She could have come out and lambasted Jolie, and she chose not to.

And what about Angie’s role?

She didn’t let it blow over. She was concerned because there was so much animosity toward her, so she went on the attack saying Aniston didn’t want to have children, which was the furthest thing from the truth. I think there’s a lot of negativity Angie exudes towards Jennifer to this day.

The Book was released last night, and to coincide with the release Brad and Angelina put a united and happy front as they went out to dinner at Dolce Vita in Beverly Hills (see pictures).
