Angelina Jolie reportedly dumped Brad Pitt because their relationship was under pressure for years because of her brother James. The claim comes from documentary filmmaker Ian Halperin, who talked to Brangelina's inner circle.

"James was so close to them that he was actually living with them," Halperin claimed. "It put Brad over the edge. Brad gave Ang the ultimatum; it's him or me!" He pointed out that Angie and James were photographed locking lips not once but twice backstage and on a red carpet back in 2000.

"I get into the whole rumors of incest. I do conclude unwaveringly in the film it was mainly a publicity stunt and it worked, but on the flip side people agree the kiss was too close for comfort," he told Radar Online, "Then the conclusion is amongst experts 'No wonder they split.' Here we are more than a decade later and James is living with them full time. Ultimately it was too close for comfort for Brad."

Rumor has it, Angie and Brad had a verbal altercation on a flight prior to their split. Ian said, "The rumor is that she reached out to James while she was on the plane to call child services, but I haven't seen the smoking gun on that point."

"It really made Brad uncomfortable how close James was. He wanted to be 'hands on Brad dad' and he didn't need another nanny because they already have so many nannies," he added, "Fast forward to present day, Angelina and James are as close as ever, and to this day they work together in the best interest of the kids. Now Ang is saying they are working together to raise them, but the damage between them is already done."
