Beyonce's sister Solange was caught wildly kicking and swinging at her brother-in-law Jay-Z inside an elevator in a surveillance video.
According to sources, the incident happened at a Met Gala after party last week at New York City's Standard Hotel.
In the video, just after Jay Z, Beyonce and Solange step into the lift, Solange starts screaming at Jay before unleashing a violent attack, at one point she even smacks the legendary rapper with her purse, TMZ.com reported.
Also a man, who seems to be a bodyguard, attempts to hold back Solange, but still she manages to hit him at least thrice.
At one point, she tries to kick him and Jay-Z grabs her foot, but never tries to strike her. Beyonce can be seen standing by without getting physically involved in this conundrum.
Then the bodyguard is seen hitting the emergency stop switch on the 12th floor, and eventually the group exits.
The trio walk out of the building together, but gop in separate cars, Solange and Beyonce in one and Jay-Z in another.
