Jay Z Fights With Beyonce's Sister.

Beyonce's sister Solange Knowles attacked Jay Z in the elevator after the Met Gala last week and video of the fight has leaked online.

TMZ released black and white footage of the physical altercation that occured at a Met Gala Afterparty held at the Stanford Hotel in NYC last Monday.

In the clip, it shows Solange and Jay Z entering the elevator then talking to each other before the youngest Knowles sister started throwing punches. Beyonce's bodyguard Julius had to intervene, but Solange was able to land few punches on Jay and also kicked him. Jay is also seen going towards Solange, but he doesn't hit her back. It appears that Beyonce tried to jump in and block Solange by stepping in front of her husband.
Meanwhile, everything seemed cool between Jay and Beyonce when they attended the Brooklyn Nets game on Saturday. They sat courtside next to each other and chatted with actor, Jake Gyllenhaal.

The couple is currently gearing up for their joint On The Run Tour.
