Beyonce’s younger sister, Solange Knowles, is seeing physically attacking her brother-in-law Jay Z in an elevator following a Met Gala after party last week. The footage from the elevator they were in has leaked, showing Solange kicking and punching the “Holy Grail” rapper while Beyonce stands next to him.

A video of the trio leaving the elevator is also public, which shows Beyonce putting on a brave face and smiling for the cameras while Solange looks noticeably mad. As Jay Z tries to get into the waiting car after her, a bodyguard prompts him to go into his own vehicle as Beyonce joins her sister.

The video, released by TMZ/, doesn’t have sound so it’s unclear what Solange is screaming at him about. However, it does appear that their security guard hit the “emergency stop” button at the height of their physical altercation as to keep it private.

Solange hits and punches Jay Z repeatedly, and he doesn’t react except for one part when he grabs her foot as she kicks him.

Daily News notes they were leaving the Standard Hotel after party in New York City when the incident occurred.
