Party animal!

Mariah Carey was spotted at The Abbey Food and Bar in West Hollywood Wednesday night. Word is she stuck around until 2am drinking shots of Beluga vodka.

“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, "She was very nice and gracious."

When the deejay realized she was in the club he began to play her songs in honour of her and dance floor blew up!

Carey took the time to take several pictures with fans but "A security guard had to stay by her booth to control her fans."
