Psycho Brad Beat Angie & The Kids!

Violent Booze-Fueled Incident on provide jet was the final straw.

DRUG-CRAZED Brad Pitt beat terrified Angelina Jolie and their kids — and his vengeful wife has the chilling photos to prove it in divorce court!

That’s the shocking charge from sources close to the couple who expose the stars’ marriage from hell in an explosive National ENQUIRER world exclusive.

“Angelina was living in fear for herself and the six children she shared with Brad,” an insider revealed. “He’d become abusive to Angie and the kids when he was intoxicated.

“He’d lash out, yelling things like, ‘I’ll punch your head off!’ ”

It was fear, sources claimed, which triggered Angie’s decision to escape from her 12-year relationship, file for a $480 million divorce — and sole physical custody of their six children: Vivienne, Knox, Zahara, Shiloh, Maddox and Pax.

Pitt, 52, has insisted he was NEVER violent with Angelina, 41, and their brood — but the FBI and child-welfare authorities are investigating abuse allegations against him after an ugly Sept. 14 incident on a private jet flying from France to Los Angeles.

During the flight, 15-year-old Maddox “was acting up and a drunk Brad flew into a red eyed fury,” dished a spy.
