Ouch! That had to hurt!!
While Lady GaGa was walking through her Romania hotel, one aggressive fan made his way through the revolving door and rushed GaGaloo.
But fortunately for her safety, her bodyguard immediately pulled the speedy fanatic out of Mother Monster's bubble and SLAMMED him into the wall!
Then he pushed him on the ground to keep him down until GaGa could exit the premises!!
Play the video to see the action for yourself (above)!!
How crazy!! We hear that with the exception of the guy's pride, everyone is fine now. He was asked to leave the hotel, though. Obviously!
