Brad Needs Protection ... from His Own Security

A security guard hired to protect Brad Pitt at an event last night wound up roughing him up instead.

When Pitt arrived to the L.A. premiere of his new film, the standard paparazzi crush ensued. For some reason a plain-clothes security guard grabbed Brad and pulled him back. Oh no he didn't! Pitt eventually broke away and reportedly exchanged words with the doomed security guard.

The first rule of fight club: Never touch Brad.

UPDATE: A source close to Brad's security tells TMZ the security team thought Brad was in danger, so they did what had to be done. Brad wasn't pissed at all at the aggressiveness of what went down -- quite the opposite, we're told.
