While most reports of Beyoncé and JAY Z's attendance at last week's Met Gala were positive and hassle-free, it appears there may have been some drama behind the scenes.

According to video obtained by TMZ, a woman who is allegedly Beyoncé's sister Solange attacks JAY Z in an elevator. There is no audio and the physical dispute was quickly broken up, but if true, this can't be good.

The photo seen above was taken of all three immediately after the supposed altercation before they left the hotel from the event. An additional video also shows a visibly upset Solange getting into a car. JAY Z attempts to get in behind her but is directed to another vehicle, although Beyoncé gets in the same car as her sister.
