At a recent concert in Detroit, Chris Brown invited  a young lady onto the stage, what happens next is a little strange. During a song, the singer/entertainer slowly removes his shirt and creeps closer to the fan. What comes next, is a little strange. Brown begins to slowly make his way towards the fan's mouth for a smooth little "smack" and then proceeds to SUCK ON HER KNEE!!!

Note, if any of you are going to see Chris Brown in New Orleans, take caution from this video. If Chris Brown pulls you up on stage, be prepared to be licked from head to knee. If you don't believe me, watch this video. By the way, the production of his show is phenomenal.
