Angelina Jolie got so mad at Brad Pitt over POLITICS and who they support for President that she threw a glass of wine in his face.

The magazine will report in this week’s issue that things got so heated that Angie empties that glass in Brad’s face an insider tells the weekly entertainment magazine. “They got into a huge fight about politics,” says an insider close to the Pitt family. (Brad, explains another insider, supports Barack Obama, while Angie’s a John Edwards fan.) “Brad ended up calling her immature. He says the next thing he knew, Angie was cursing at him and throwing a glass of wine in his face.”

Brad, understandably, was speechless. “He was left standing there with wine dripping down his face onto his clothes,? says the insider, “before storming off to wash up and change. He says he was absolutely disgusted by Angelina’s behavior.?

This relationship would already be over if 542,156 kids weren’t involved. Even with so, it’s only a matter of time until Bradgelina implodes.
