Celebrity watchers were shocked to see a video reportedly showing Jay Z and his sister-in-law Solange involved in a fight...
The pair, who had attended a Met Ball after party in New York City, were leaving the Standard Hotel with Beyoncé when the argument broke out.
A CCTV video, released by TMZ, shows blurry clips of the attack which took place in the elevator.

In the short clip Jay Z is seen fending off Solange, 27. Although the footage is not high- resolution, it does look as though Solange is restrained by a bodyguard while her sister Beyoncé stands by. The Single Ladies singer intervenes but mainly to untangle her gown from the scruffle.

It is unclear what triggered the fight and, as the website reported, the bodyguard stops the elevator at the 12th floor, presumably to keep the argument private.
When the trio emerge from the lift and walk out of the building, paparazzi catch Solange and Beyoncé getting into a car together while Jay Z steps into a different vehicle.
Earlier at the star-studded gala, the family had shown no signs of a disagreement. Beyoncé posted a photo of her and her husband cuddling up to each other at their table.
