Ten months after welcoming twins Moroccan and Monroe, Mariah Carey hit the stage to perform at Caesar's Entertainment Kicks Off "Escape to Total Rewards" at Gotham Hall in NYC.

Clad in a skintight black dress and dripping with diamonds, Nick Cannon's wife, with a full band and backup dancer, sang hits like "It's Like That," "Obsessed," "I'll Be There," and a new version of "Shake You Off."

"It's my first performance since having dem babies!" the Grammy winner announced as the crowd cheered. (She and Cannon, 31, welcomed their bundles of joy April 21 of last year.)

Having some trouble with her earpieces during the show, she joked that the devices were "fitted pre-baby…they don't fit anymore!"

She gushed of her little girl and boy: "Do you love them babies? Cause I do. . . 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."

Regardless, in abstentia, she dedicated "Always Be My Baby" to her kids.
