Celebrity news site TMZ has just published elevator security camera footage that shows Solange Knowles attacking Jay Z. The video was recorded at the New York Standard Hotel, after last week's Met Gala.
There is no word on what triggered the explosive physical altercation. However, Solange (Beyonce Knowles' sister) is seen repeatedly attacking Jay Z, even after being restrained by someone who appears to be a bodyguard. Beyonce, who is in the elevator, does not participate in the altercation.
At one point, you can see the bodyguard hit the elevator's emergency stop switch on the 12th floor, which TMZ says was to "presumably to keep the fight private."
Prior to the elevator exchange, TMZ is also reporting that Solange left the Met Gala after party at the same time as Jay Z and Beyonce. However, Solange and Beyonce were escorted to one car, while Jay Z rode alone in another.
