On Sunday May 4th Beyonce and Jay-Z attended the Met Ball together, putting on a loved-up display on the red carpet, complete with a comic moment where Jay-Z joke ‘proposed’ to Bey after picking up her runaway ring. Solange meanwhile went solo in a 3.1 Phillip Lim dress. Everything seemed peachy on the red carpet and inside the ball, Beyonce hung out with Solange and Lupita Nyong’o as seen in a picture uploaded to the singer’s Instagram. Bey also shared pictures of her self and Jay-Z seemingly having a great time inside the star studded gala.

But it appears that once the stars headed to the after party the drama unfolded. US Weekly is now reporting that, prior to the infamous elevator altercation, Solange found herself in an argument with fashion designer Rachel Roy, a close friend of Km Kardashian. Onlookers are reported to have seen Solange yelling at the designer before Beyonce “got in the middle of it.” There’s no word on what the disagreement could have been about, but Solange and Rachel were actually each other’s date for the night at the Met Ball two years ago. However, Roy’s ex husband Damon Dash has had a very public falling out with Jay-z after the pair ended their business relationship.

At some point later in the evening, the trio of Beyonce, Jay-Z and Solange decided to call it a night and that’s when the drama took place. In the video obtained by TMZ and taken from the surveillance camera of the Standard Hotel's elevator, Solange can be seen lashing out at her famous brother in law who doesn't retaliate, while another man intervenes and Beyonce looks on.

The video has no audio so we’re all in the dark about what actually could have been said by either party to cause such an altercation. If you want the internet’s guesses, #whatJayZsaidtoSolange has been trending ever since the footage went viral. All that’s really been reported is that Solange ‘'overreacted'' to something Jay-Z said. A source told US Weekly “Solange flipped out over something Jay had said, that she took the wrong way”, and added that they weren't, “sure what it was, but she greatly overreacted.’'
