NEW: Hotel releases statement

TMZ released video that it claims is of a fight

Beyonce and Jay Z are headed on tour this summer

CNN  — 

A video that TMZ alleges is of Beyonce’s younger sister having an altercation with the superstar’s husband, Jay Z, has surfaced online.

TMZ says the surveillance video is from an elevator and was taken the night of the Met Gala this month in New York.

A woman who resembles Beyonce stands in the corner of the elevator during most of the altercation. Jay Z is Beyonce’s husband and Solange’s brother-in-law.

It’s unclear what caused the fight.

Representatives for Solange, Jay Z and Beyonce have not responded to CNN requests for comment.

Shortly after the video was released, the hotel said it was “shocked and disappointed” by the breach of security.

“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,” the statement said. “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.” Watch the video

Beyonce and Jay Z recently announced their “On the Run” tour, which is scheduled to take them to 16 cities this summer.

Some found humor in the unverified video, mocking Solange Knowles, who is also a singer. One tweeted, “Jay Z must have shown Solange her album sales on a line graph.”

The memes also came fast and furious, as well as tweets with the hashtag #WhatJaySaidToSolange.

One featured a picture of Solange and the caption “Solange attacks Jay Z? The first hit she’s had in years.”

Another used photos of actor Jake Gyllenhaal courtside with Beyonce and Jay Z at a recent basketball game. The caption imagined Beyonce saying to Gyllenhaal “…And then Solange was kicking him and screaming in the elevator” before Jay Z turned to the actor and said in the caption “…And she just stood there,” gesturing to Beyonce.

TMZ reports that Beyonce left after the incident with her sister while Jay Z took another car.

HLN’s Marc Balinsky contributed to this report. CNN first learned of the alleged fight video from Twitter.
