Chris Brown just BLEW OUR MINDS!!! 'Cause the singer put his graffiti skills on display on a wall in Florida ... and dude's got some serious talent.
Brown grabbed a spray can and went to town on a building in Miami (we're guessing he was contracted to be there, 'cause if he wasn't, it could be considered vandalism and he could be arrested ... probation violation ... jail ... court drama ... etc.)
Photogs snapped pics as Brown tagged the canvas ... and you gotta trust us on this one, the finished product is pretty awesome.
