Brad Pitt & Angelina Jolie kids turn nasty!

Brad Pitt and Angelina Jolie are having trouble with their children again!

According to the latest issue of American tabloid the National Enquirer, the couple who raise six kids together are dealing with the fact their four eldest have turned violent, with the main troublemakers being the oldest boys.

Jolie and Pitt reportedly pulled their 7-year-old son Pax out of an exclusive private school after he punched a classmate.

“They’re the most famous kids in the world, but it seems as if the older they get, the more violent and belligerent they become,” a source said.

“Brad and Angelina are good parents, but their close-in-age instant family has proven difficult to manage even with nannies and household staff. It’s beyond chaos, and it’s driving Brad and Angelina crazy.

“The Jolie-Pitt household has almost become a war zone, with kids screaming, punching and scratching each other.

“There are fights between Maddox and Pax, while Zahara and Shiloh regularly throw temper tantrums and violently throw things when they don’t get their way.

“The girls have been involved in fighting and shoving matches with each other and with the boys.

“Maddox likes to fight for fun.

“His wrestling matches and war games with Pax are completely out of control. They throw everything from food to sharp-edged toys at each other, and their brawls often lead to scraped arms and knees, cut faces or bloody noses.

“Brad tries to keep Knox and Vivienne protected and out of the fray.

“With six young children so close in age, and trying to blend biological and adopted kids, it seems they’ve bitten off more than they can chew.”
