A hotel in New York says it is investigating the leak of a security video that appears to show Beyonce’s sister, Solange, attacking Jay Z.
A statement from its owners confirmed that they were looking into how footage from one of its lifts was released.
“We are shocked and disappointed that there was a breach of our security system and confidentiality we count on providing our guests,” it said.
Beyonce’s management has declined to comment on the TMZ story so far.
The video was released by celebrity gossip site TMZ.
The footage appears to show Solange trying to kick and hit Jay Z in front of Beyonce. A security guard is then seen restraining her and appears to attempt to stop the lift.
It’s thought the incident happened after the three had attended the Met Gala Ball last week in New York and a party at the hotel afterwards.
The hotel added: “We are investigating with the utmost urgency the circumstances surrounding the situation and, as is our customary practice, will discipline the individuals involved to our fullest capacity.”
The Standard, High Line, is an 18-storey boutique hotel located in Manhattan’s Meatpacking District.
The chain also has hotels in Los Angeles and Miami Beach, Florida.
Newsbeat has contacted Jay Z’s management but so far no-one has returned the emails.
Solange is Beyonce’s younger sister and is a singer-songwriter in her own right.
The 27-year-old recently performed at Coachella music festival in the US, where Beyonce joined her on stage for a surprise guest appearance.
Jay Z, 44, and Beyonce, 32, married in 2008.
They start their US co-headlining On the Run Tour in Miami on 25 June.
