Mariah Carey made her first appearance since giving birth to twins, Moroccan Scott and Monroe, 3 months ago. She partied with a few close friends at Juliet Supperclub in Chelsea, New York. According to sources, Mariah spent most of the night posing for pictures, dancing with friends, and sipping out of a $1,600 bottle of Angel champagne. With husband Nick Cannon in Vegas for the weekend, it looks like Mariah just wanted a "ladies night out". Check out some photos of her night after the jump.
