The explosive documentary that is allegedly going to spill some big secrets about what led to Angelina Jolie and Brad Pitt's shocking divorce may also have some insider knowledge about the Allied actor's first famed split with Jennifer Aniston.

The reveal that Aniston and Pitt were splitting after five years of marriage back in 2005 devastated fans of the then super-couple, and when photos emerged of Pitt vacationing with Jolie and her adopted son Maddox shortly after, it led to many taking sides and pitting the two women against one another, a trend that has still continued through the years despite Jolie and Pitt eventually marrying and welcoming five more kids together, and Aniston also moving on and marrying Justin Theroux.

Now though, the documentary Broken: The Incredible Story of Brad and Angelina, which is slated to air in a few weeks (though it is unclear where), is reportedly also set to reveal a bombshell about the unraveling of Pitt's first marriage, and absolve Jolie of all the blame.

"Brad and Jen were having serious issues for a long time before Ang came along," a source from the production reportedly told Radar Online, "This film will finally reveal the real reason Brad and Jen split. If it wasn't Angelina Jolie it would have been someone else! The film clearly shows there is a pattern in his behavior in relationships."

The insider also alleges that regardless of who was really to blame for Pitt and Aniston's divorce, she has since realized she got lucky with her marriage ending when it did because of everything that has allegedly happened with Pitt over the years since.

"It seems like Jen really feels like she dodged a bullet with Brad," the source claimed. "Jen seems shocked at the path that Brad went down in the past 12 years. Some of the allegations against him are unfounded, but the accusations of alcohol and drugs are not, and its all revealed in the film."

Aniston has mainly stayed out of the drama regarding her ex's current split and divorce, though her name was dragged into it early on because of the history, which eventually led to her current husband Theroux speaking out about it and trying to get his wife's name taken out of the conversation.

"As a child of divorce, all I can say is that's terrible news for those children and that's all you really can say," he said at the time. "It's boring to sort of comment on anything else. People are having a bad time. That's horrible."
