Jay-Z is a Punk

We heard the drumbeats from UltravioletUnderground about this video clip with a nationally known celebrity.

Villagers, does it appear that Jay-Z is pimp-slapping a young girl (pony-tail and all)? What could cause him to do something like this to a young girl in front of his posse? Any why didn't any of them come to her defense? Villagers, what say u?
