Take note, Little Monsters: When you try to approach Lady Gaga for an autograph, move slowly and try not to fling yourself at Mother Monster or this might happen to you.
Check out this video of Gaga's bodyguard taking down a fan. It happens in Romania while Gaga is walking through her hotel. A male fan runs over and just about lunges at her — and he's immediately knocked to the ground by one of her bodyguards as Gaga flinches away.
The poor guy probably wasn't trying to cause trouble, but Gaga's boys take no chances. They should be Secret Service agents.
