Her hubby Nick Cannon was acting as guest DJ at the Cabana One nightclub at the Mayfair Hotel and Spa in Coconut Grove when his super-famous wife Mariah Carey made a surprise appearance.

Carey turned up at the end of Cannon’s set, unable to keep her presence concealed when Nick repeatedly played her songs. Like a scene out of Glitter, Mariah just went ahead and grabbed the mic, singing along to her own song.

But the best part of the evening was seeing how Mimi likes to drink her wine. The voluptuous pop star sipped her glasses of red wine with a straw. According to a spy who dished to the New York Daily News, “When she and Nick left at 2 a.m., Mariah took a glass of wine down in the elevator with her.” Hmm, time for her to do some loving u long time?
