An eyewitness at the roller rink tells ET that Bey and Jay arrived "close to midnight" and "took the private area above the rink with people like their assistants."
"She was quiet, didn't interact with fans much but was chill," according to the eyewitness. Bey was spotted wearing a black cap, a black off-the-shoulder shirt reading "black magic" and distressed jeans.
The "Formation" singer later headed down to the rink, where she skated alongside the other patrons. The eyewitness notes that the couple's security "wasn't super heavy" during their outing.
"She came in very low-key and dressed as anyone else, very under the radar," another eyewitness tells ET. "She did skate with fans, but then more and more people began to notice and crowd around her to much, to where it was hard for her to skate. The rink did stay open for her and her entourage a few hours after the session so that she can have a private party to herself and enjoy the skating rink."
