Beyonce’s Sister Attacked Jay Z In Elevator

Solange Knowles Allegedly Attacks Jay Z In An Elevator As Beyoncé Looks On

We really want to know #WhatJayZSaidToSolange, too.

Jay Z and his sister-in-law, Solange Knowles, appeared to get into an altercation on their way to a Met Gala afterparty in New York City last week.

TMZ posted surveillance footage from inside an elevator at the Standard Hotel where Jay Z, Beyoncé, and Solange were headed up to a bash at the Boom Boom Room when, all of a sudden, the DJ allegedly lost it on the rapper.

In the video, a woman understood to be Solange, 27, aggressively confronts a man believed to be Jay Z, 44, about something, and after the two appear to exchange words — there is no audio in the footage — she starts punching and shoving him. The rapper, however, does not hit back. A bodyguard-type then separates the two, but despite being restrained, Solange starts kicking her brother-in-law. A woman believed to be Beyoncé can be seen standing next to her husband although she never gets physically involved.

TMZ notes that the bodyguard hit the emergency stop switch on the 12th floor (mid fight) presumably to keep the altercation private.

It's unclear what triggered the disagreement, and reps for Jay Z, Solange, and Beyoncé have yet to comment on the matter.

The Standard released the following statement on Monday: "We are shocked and disappointed that there was a clear breach of our security system and the confidentiality that we count on providing our guests. We are investigating with the utmost urgency the circumstances surrounding the situation and, as is our customary practice, will discipline and prosecute the individuals involved to our fullest capacity."

Last Tuesday, Beyoncé posted a photo alongside Solange, Lupita Nyong’o, and Sarah Paulson at the Met Gala afterparty, smiling like nothing was wrong.

However, when the trio was photographed leaving the Standard Hotel post-fight early Tuesday morning, Solange looked visibly upset exiting the soiree ahead of her older sister and Jay Z. The 32-year-old "XO" singer and Solange got in one car together, while the "Holy Grail" rapper left in a separate vehicle.

On May 7, Bey shared the following prayer on Instagram, which may or may not be related to the elevator incident:

The altercation is shocking as Beyoncé, Jay Z, and Solange are a notoriously tight-knit group.

Just last month, Beyoncé and Jay Z attended both weekends of Coachella in Indio, California, to support the R&B singer, who was performing at the festival. (Beyoncé even came out on stage during Solange's weekend 1 gig.)

Whatever the fight was about, the family seems to have moved on.

On Saturday, Solange's son, Juelz, watched the Brooklyn Nets beat the Miami  Heat 104-90 with his famous aunt and uncle at Barclays Center.
