Looking flawless at the Met Gala were superstar singer Beyonce and her husband Jay Z, and also Beyonce’s sister, Solange Knowles flashing a 1000 watt smile but who would have thought there was some kind of trouble between Solange and Jay Z.

According to gossip site, TMZ, Solange viciously attacked Jay Z as they left the Met Gala last Monday.

The 27-year-old was caught on surveillance camera lashing out wildly at her brother-in-law, 44, with both her arms and her legs, while her sister stood beside them helplessly.

The trio stepped out of the elevator later like nothing had happened at all.

It is not clear what started the fight making Solange go wild, fighting her sister’s husband.
