Solange Attacks Jay Z in an Elevator [VIDEO]

File this under strange. Jay Z was violently attacked by his sister-in-law Solange inside an elevator at a Met Gala after-party last week at the Standard Hotel in NYC.

TMZ has obtained surveillance footage from the bizarre incident.

Jay Z, Beyoncé, and Solange step into the elevator. Solange can be seen screaming at Jay before physically assaulting him, kicking and swinging at him.

A bodyguard attempts to hold her back, but she manages to land a kick before Jay grabs her foot. Meanwhile, Beyoncé stands back and eventually gets in the middle of them to block the fight.

At one point, the bodyguard hits the emergency switch on the 12th floor to stop the elevator from opening.

It’s unclear what triggered the fight. The photo above was taken as they left the party, and Solange is clearly not happy.
