We know Angelina Jolie wears the pants in her relationship with Brad Pitt, but will her insane, jealous rages ultimately drive her man away for good?


That's what OK! surmises in its new cover story.

The Oscar-winning actress is allegedly GOING NUCLEAR over Brad Pitt's flirtatious relationship - documented in photographs!!!!! - with a young assistant.

Just look at their chemistry on the Malta set of his new zombie thriller, World War Z. He's standing NEXT TO HER! No wonder Angie's blowing her top:

According to this reliable source, Brad's "flaunting" happiness on purpose!

"Brad resents Angelina tries to control him," a source says. "He told Angelina outright, 'I've always had women friends, I'm always going to. End of story.'"

Jolie puts on a good front as a woman of confident - even arrogant - sensuality, but the world-saving mom has some insecurity issues, OK! states.

Slowly but surely, it's driving Pitt crazy ... mostly.

"Of course, there's a part of him - even though he would never admit it - that likes it," the insider reveals. "Angelina is usually so cool, unaffected."

"She's this kind of untouchable woman, and when she shows some jealousy, it lets him know she has a weak spot - and that she's crazy about him."
