Beyoncé Knowles, Solange and Jay Z have finally spoken out about the crazy attack that went viral this week; and Solange isn't the only one who takes the blame for what went down.

Solange Doesn't Like the Way Jay Z 'Controls' Beyoncé?

The trio seemed to be a united front when they released a joint statement to the Associated Press that read:

"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."

Beyoncé on Solange's Side?

A surveillance video of Solange attacking Jay Z in an elevator and Beyoncé stood by hit the internet earlier this week. The two were leaving a Met Gala after party. While it's clear Solange was furious about something, with the video having no audio, fans have been trying to put the pieces together themselves.

One insider has stepped in to help give a little insight. They told E! News that the entire thing went down because of celebrity designer Rachel Roy. Roy is the ex-wife of Jay Z's former business partner, Damon Dash. Jay Z is also the Godfather of Roy and Dash's daughter, Ava.

The insider said Roy was being extremely "flirtatious" with the Tom Ford rapper at the Met Gala. It only got even more heated once they all went to the Boom-Boom room for an after party. That's when Beyoncé decided to step in and tell her to stop being "disrespectful" and to stay away from her family. Solange then came to defend her sister.

"Things got heated with [Solange] and Rachel. Jay said some disrespectful things to Beyoncé and Solange as the confrontation was going down. That's why all hell bore loose in the elevator and why Beyoncé just stood back and let Solange hit Jay."

The source's account could be true considering it was reported that Solange got into a screaming match with Roy at the party. It also lines up with TV talk show host Wendy Williams' theory as well. Check it out in the video.
