While Brad Pitt is reportedly being investigated by the L.A. County Department of Children and Family Services and possibly even the FBI over claims he became “verbally abusive” and “physical” with his children during a flight on a private jet, a “source close to the actor” is speaking out to tell Pitt’s side of the story.

In an interview with People, the source admits that Pitt “was drunk, and there was an argument between him and Angelina,” when one of the couple’s older children “then got caught in the middle, literally. He stepped in front of Brad. There was a parent-child argument which was not handled in the right way and escalated more than it should have.”

However, the source vehemently denies claims that Pitt hurt the child. “He is emphatic that it did not reach the level of physical abuse, that no one was physically harmed,” adds the source. “He did not hit his child in the face in any way. He did not do that; he is emphatic about that. He put his hands on him, yes, because the confrontation was nose to nose and was spiralling out of control.”

Furthermore, the source is adamant that any allegations beyond that are “a combination of exaggerations and lies,” and blames “sources close to Jolie” for spreading the alleged misinformation. “They have taken the overall smallest kernel of truth — that a fight in which Brad was somewhat inebriated got out of hand and reached a regrettable peak, and that as a result DCFS is looking into it — and they are manipulating it to best suit their attempts to gain custody.”

Contrary to unsubstantiated reports, claims the source, the “Fight Club” star “was not black-out drunk” and “he absolutely remembers that evening and has been interviewed at length to that effect.”

Meanwhile, “a source close to Pitt” previously told People that Pitt “takes the matter very seriously and says he did not commit any abuse of his children. It’s unfortunate that people involved are continuing to present him in the worst possible light.”

ET Canada reached out to the FBI and received the following statement about reports that Pitt is being investigated by the Bureau: “In response to your inquiry regarding allegations within the special aircraft jurisdiction of the United States; specifically, an aircraft carrying Mr. Brad Pitt and his children, the FBI is continuing to gather facts and will evaluate whether an investigation at the federal level will be pursued.”
