Washington, July 27 (ANI): Brad Pitt and Angelina Jolie's constant bickering has forced their son, Maddox, to plead his father not to leave them ever.

Recently, Maddox happened to witness one of the couple's major fights, wherein Jolie blamed Brad for the poor box-office performance of her movie A Mighty Heart, which he produced.

"Brad rarely raises his voice, but this time he told her enough's enough," Life and Style Weekly quoted an insider, as saying.

Maddox, accompanied by his brother Pax, stood astounded, as his parents screamed at each other.

"Brad turned to the boys and quickly asked them to go into the other room," the insider said.

The source added that the couple's arguments turned so ugly that Maddox once tearfully asked his father not to leave them.

"The fighting really upsets him. It often makes him cry - and he ends up begging his parents to stop fighting," the insider said.

However, a rep for Pitt recently rubbished the reports and insisted that Brad and Angelina were facing no trouble at all in their relationship.

"They are together on vacation and all is well," the rep said. (ANI)
