Solange Knowles' Attack On Jay-Z: Beyonce Breaks Her Silence On Met Ball Brawl

Beyonce and Jay-Z have broken their silence over the former's sister, Solange Knowles, attacking the latter in an elevator after the Met Ball 2014.

The incident, which was leaked through a surveillance video by a now fired member of staff at The Standard Hotel in New York, showed Solange lashing out at her brother-in-law while Beyonce did not get involved.

Since it came to light, there has been much speculation about what caused the outburst. However, in a joint statement, Beyonce and Jay-Z have denied rumours Solange was drunk and said they have "moved forward as a united family".

It reads as follows: "As a result of the public release of the elevator security footage from Monday, May 5th, there has been a great deal of speculation about what triggered the unfortunate incident. But the most important thing is that our family has worked through it.

"Jay and Solange each assume their share of responsibility for what has occurred. They both acknowledge their role in this private matter that has played out in the public. They both have apologized to each other and we have moved forward as a united family.

"The reports of Solange being intoxicated or displaying erratic behavior throughout that evening are simply false.

"At the end of the day families have problems and we're no different. We love each other and above all we are family. We've put this behind us and hope everyone else will do the same."

Unsurprisingly, the couple are probably hoping speaking about the incident will quash and halt rumours and speculation around the attack, which have both been rife since the start of the week.

While some have claimed Solange was angry at Jay-Z for getting "too close" to designer Rachel Roy, others believe she did not want her brother-in-law to party with Rihanna as planned later that night.
