This is so alarming!!
In the video clip, you can see the Losing You singer losing her cool, kicking crazily towards Jay's side of the elevator, and swing hard at him while being held back by another man.
According to sources close to the incident, it happened at a Met after party last week at the Standard Hotel, and the violence began after Solange started screaming.
Yoncé's little sis made contact with the rapper at least three times, and he never attempted to strike back!
Beyoncé stood to the side during the entire ordeal and did not get involved.
No word on what triggered the violence, but we're sure we'll find out sooner or later!
