TMZ dropped a bombshell of a video today that shows an altercation between Jay Z and Beyonce's Sister Solange.

The physical altercation happened in a elevator at the Standard Hotel in NYC last week, in the video below you can see Beyonce', Jay Z, Solange and what TMZ assumed is a bodyguard, enter the elevator.

After the doors close, Solange punches and kicks at Jay Z several times while the bodyguard gets in between the two. Jay Z appears to remain calm during the situation, only blocking the hits and grabbing her foot at one point after she kicked him.

No word on what caused the altercation, but in another video on TMZ, you can see them all leaving the hotel and all getting in separate cars after leaving the elevator.
