Jay-Z Physically Attacked By Beyonce’s Sister

A video, posted by TMZ, allegedly shows Solange Knowles attacking Jay-Z in an elevator at after partying in celebration of the Met Gala last week. The crazy surveillance video,  shows a her entering the elevator with a man in a white tuxedo (Young Hov) and pushing, punching and kicking him as another man tries to hold her back. Interestingly the man presses the emergency button on the elevator… Maybe to keep it private?
