Watch: Mariah Carey's First Post-Baby Performance

Mariah Carey was her true diva self last night when she returned to the stage just 10 months after giving birth to twins.

Mariah, 41, showed off her slender post-baby figure in a form-fitting long black gown while performing a 40-minute set at New York's Gotham Hall. She delighted the crowd with signature favorites like Always Be My Baby, We Belong Together and I'll Be There.

Mariah gave a shout-out to her hubby Nick Cannon, who was in the building, and said she missed her twins 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."

The show was part of the multi-city "Escape To Total Rewards" event -- sponsored by Caesars Entertainment -- which also included performances by Celine Dion, Cee Lo Green and Maroon 5 at locations across the country.
