The Met Gala was last week and while it is a fundraiser for The Met it really is just a who's who of Hollywood!

Celebs come out in droves dressed to impress. But just because you have on your Sunday's best doesn't mean you behave like you're in church.

Surveillance video has emerged showing Solange Knowles, the younger sister of Beyonce, beating up Jay-Z. And as we all know Jay-Z and Beyonce are married.

What the heck is going on?

As of the posting of this article, no reason has been given as to the altercation, but it sure does look crazy.

In the video Beyonce never physically steps in, but I'm sure if there was audio we would hear her trying to calm the situation. I so wish there was audio.

I give kudos to Jay, who never physically gets back at her. He grabs a foot at one point, but I think that was more in defense than anything else.

The trio were seen leaving The Met Gala together, however, Beyonce and Solange left in a separate car than Jay-Z.

Looks like Jay-Z's got 99 problems and his sister-in-law is one!
