Video Of Solange Allegedly Attacking Jay Z After Met Gala Surfaces

Video has surfaced of what appears to be Jay Z and Beyonce's sister Solange Knowles getting into an altercation while in an elevator after the Met Gala.

In the 58-second clip obtained by TMZ, Solange can apparently be seen confronting her rapper brother-in-law while Beyonce stands by. Another man holds Solange back until the elevator stops and the three exit. The trio had been together at the Met Gala after-party at the Standard Hotel in New York City on May 5.

In a separate video taken by Splash, the three can be seen exiting the elevator and walking past a group of photographers. Beyonce and Solange enter a waiting car while Jay Z walks into a different SUV.

"Solange flipped out over something Jay had said, that she took the wrong way," a source told Us Weekly of the incident. "She took it too hard or too far. Not sure what it was but she greatly overreacted."

Reps for both parties were not immediately available for comment.
