Report: Beyonce And Jay Z Are "Used To" Solange's Outbursts

We were shocked to see the footage of Solange Knowles attacking Jay Z in an elevator at the Standard Hotel after the Met Gala last Monday, but according to a source for Us Weekly, this is "not the first time this has happened"!

A source tells the mag:

"That's why Bey and Jay were so calm. They are used to this from Solange. It has definitely happened before. She is genuinely a sweet and nice person but she also keeps sh*t real. She can take a small thing and it triggers her."

This still doesn't explain WHY though -- we're dying to know what set off Solange!

We're not sure if this is in any way related, but it looks like Jay Z wasn't the only one who felt the wrath of Solange last Monday. Apparently Beyonce's little sister yelled at pal Rachel Roy and a group of people at the after party at the Boom Boom Room, and during the squabble, a source tells Us Weekly that Beyonce "got in the middle of it."

However, before that, a source tells the mag that the sisters (and Naomi Campbell) appeared to be having a good time dancing at the bash while Jay Z "hung back at one of the fireplace areas." The same source added that the trio "abruptly" left, but no one is sure why.

Still, another observer at the Met Gala notes that Beyonce seemed "off" that night. "She wasn't smiling, was hardly with Jay, she was off with Solange the whole time," the spy dished. After the squabble Beyonce and Solange got in a car together while Jay Z found another ride, and an insider tells the mag, "It is a testament to Beyonce's calm nature how she kept back and played the peacekeeper here. She is so calm and always the peacekeeper."

As far as the video leaking online, a staffer at the Standard tells the mag, "The video was recorded on a cell phone from the monitors in the back room."

But what happens now? Is anyone going to make an official statement about this? Beyonce posted the message below on her Instagram on May 7, but keep in mind this was before she knew that the tape was leaking online:



This has to be about Solange, right? Or are we reading too much into this?
