Mariah Carey: The First Post-Baby Performance!

Looking skinny and sounding as great as ever, Mariah Carey took to the stage in New York City last night for the first time since giving birth 10 months ago.

"Do you love them babies?" she asked the crowd at one point of Moroccan and Monroe. "I really wanted to bring them here tonight, but Monroe is sometimes shy and takes a while to warm up to an audience. Rock and roll! Nah, but it's late. It's time for them to be asleep."

Donning a skintight black dress and covered in diamonds, Carey broke into such tracks as "It's Like That," "Obsessed," "I'll Be There," and a new version of "Shake You Off." Watch the latter below:
