Jay Z has 99 problems and sister-in-law Solange probably accounts for most of them.

An elevator security camera video was leaked to TMZ on Monday that appears to show the younger Beyonce sister ferociously assaulting the rapper as all three step into an elevator at The Standard Hotel in New York City.

The incident took place at an after-party for the Met Gala, which took place on May 5. The video shows Solange going slap happy crazy on Jay Z as Beyonce looks on. A security guard attempts to restrain Solange, but she still manages to get in a few hits and kicks.

There is no word on what triggered the fight.
