Brad Pitt Begs "Please, Please, Please Marry Me Already"

In today's bullshit Brad Pitt and Angelina Jolie story, they're getting married! Yay! Except that if they got married every time a magazine said they would, they'd have more ceremonies under their belts than Larry King. Says OK! magazine (via Celebitchy):

Superstar parents Brad Pitt and Angelina Jolie are the worldís most glamorous couple ó but one thing has been missing from their seemingly perfect lives: A marriage certificate.

Now a friend of the pair tells OK! that Brad, 45, has issued Angie, 33, an ultimatum: ìBradís told her, ëMarry me, or itís over.í î

Whatís more, another source says, Brad told Angie ó who hopes to add to their six children ó ìhe definitely wants to get married before they have any more babies.î

Why is Brad putting his foot down? While his Oscar-winning baby-mama frantically pursues film and humanitarian work, heís essentially been a single dad ó and heís ìstressed out,î a friend of Brad tells OK!.

Both Brad and Angie ó now holed up at NYCís posh Waldorf Astoria hotel while she films the spy thriller Salt ó are even too fried for sex. ìTheir relationship is so out of kilter, he believes marriage is the only thing that will bring it back around.î

Wait, Brad thinks that getting married will result in more sex? His one experience with matrimony was with Jennifer Aniston, and we're guessing she's the only-on-weekends type.
