"There was no formal announcement that she arrived at the club, but she and her friend B. Scott held court at one of the main dance floor tables – so she was very visible," a partygoer tells PEOPLE of the singer, who recently renewed her vows in Paris. "She was very nice and gracious."
In honor of Carey's appearance, the deejay started playing her songs, which caused the ladies on the dance floor to "go crazy," the source says.
Even though the pop diva, who stuck around until 2 a.m. and took some shots of Beluga vodka, kindly posed for pictures with many people at the club, the insider explains, "A security guard had to stay by her booth to control her fans."
