Mess with Lady Gaga and her Little Monsters will come after you. And by Monsters, we mean her bodyguards. And by little, we mean effing huge.

While leaving her hotel in the Romanian capital of Bucharest, a fan snuck past security and got right in Gaga's face to ask for an autograph. Clearly, that was a bad move. Within a second, Gaga's bodyguard slammed the guy's head against a door and threw him to the ground!

After picking himself up, the fan escorted himself out of the building and did not appear to have any injuries. No charges were filed afterwards. It does seem like the bodyguards handled the situation effectively while using the appropriate amount of force. Given how crazy some fans can get, especially Lady Gaga's, you can never be too careful.

Check out the video of the incident below!
