This isn't good...

Brad Pitt is under investigation by the L.A. County Dept. of Children and Family Services for child abuse, TMZ reports. The actor allegedly got verbally and physically abuse with his children aboard a private jet last Wednesday, and someone on the flight anonymously reported it to authorities. This explains why Angelina Jolie filed for divorce and requested sole custody!

The World War Z star reportedly got wasted and went crazy, and when the plane landed around 8pm, he continued to rage on the tarmac and even tried to flee the scene in one of the fuel trucks. Yikes!

The couple have already been interviewed by DCFS, and they plan to interview all six kids too. The investigation is ongoing.

"He 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," a source close to the A-list hunk told the news outlet.

All of Angie's statements since news of the split broke have referenced the safety of her kids, and now we understand why. We think it's only a matter of time before Papa Pitt checks into rehab!
