Elevators are never as private as you might think, even for a notoriously shielded A-list couple.

TMZ posted a video today of what appears to be Solange Knowles (Beyonce’s sister and a music star in her own right) repeatedly hitting and kicking her brother-in-law, Jay Z, as the trio rides in an elevator at the Standard Hotel.

The minute-long clip, taken via a security camera, went viral almost immediately. It’s apparently from after a Met Gala party (you can see here that their outfits are the same) in New York City last Monday.
