Angelina Jolie said her ex-husband Brad Pitt was "becoming a monster" when he allegedly flew into a drunken rage during a 2016 fight on a plane that left their children scared, according to explosive FBI documents recently obtained by People magazine.

Jolie, 47, told authorities that Pitt "ranted" on the private flight from France to Los Angeles in front of their six children and "mimicked the behavior of a monster," screaming at them, People reported

The kids were "shell-shocked" during the Sept. 14 blowup, said Jolie, who added that she was "frozen, scared and didn't know what to do" in the moment, according to the documents. 

Pitt, 58, allegedly pounded the jet's ceiling, shook her and shoved her into a wall. She said she felt "like a hostage."

When it looked "like he was going to attack" one of their children, who had called him a "prick," she admitted that she put her arm around his neck and squeezed. 

The "Girl, Interrupted" star told officials that Pitt poured beer on her, spilled wine on the floor and caused approximately $25,000 in damage to the jet. Both parties reported injuries.

Earlier this year, Jolie filed a Freedom of Information Act (FOIA) lawsuit under the pseudonym Jane Doe to obtain the FBI report related to the alleged assault, which was first confirmed by journalist Eriq Gardner of Puck.

A source close to Pitt said Jolie only requested the documents to revive the ugly incident and inflict pain on her ex-husband.

Pitt and Jolie have been in possession of the report for years, the source told People.

The Hollywood heavyweights finalized their divorce in 2019 but have continued to battle over custody and a French winery the pair bought together in happier times. 

Pitt accused Jolie in a lawsuit of selling her stake in Chateau Miraval to a Russian oligarch behind his back to wound him. 

The resurrection of the FBI report is the latest strike, the source said.

"It's wave after wave of attempts to hurt him," the source added. "What are the motivations of a person to take up court time and public resources in filing an anonymous FOIA request for material they have had for years? There's only one: to inflict the most amount of pain on her ex. There is no benefit to this. It is harmful to the children and the entire family."
