SHOCKER: Solange Knowles Attacks Jay Z In An Elevator, Beyoncé Stands By Patiently

The first crack in the picture perfect facade that Beyoncé and Jay Z have created with their envied relationship has emerged as video footage of the superstar's younger sister, Solange Knowles, attacking the Roc Nation mogul in an elevator.

Taking place at a Met Gala afterparty, the video apparently shows Solange arguing with her sister's husband, before taking a more aggressive approach by hitting and kicking him as a bodyguard tries to restrain her without much luck. Beyoncé, on the other hand, stands by and watches the action unfold. She is seen exchanging words with both parties at times and briefly steps in between them. Oh, what I would give to be a fly on the wall.
