Angelina Jolie and Brad Pitt were a couple for over 11 years, but now, the mother-of-six claims the Oscar winner, 52, has anger issues that make him an unfit parent.

"If it was just one thing, like Brad smoking a lot of pot, she would have been willing to work through that, but that's not it at all," a source tells Life & Style. "This is of a serious nature. And yes, she will bring it out in family court."
