The Butterfly Diva is Back and Hot!

Mariah Carey, who’s 41-year-old, arrived at Gotham Hall in New York to perform for the Escape to Total Rewards event on the arm of her husband/babydaddy Nick Cannon, and she looked Great! The mother-of-twins flaunted her figure in a tight-fitting one-shouldered black dress, which clung to her body. It accentuated her 70lb weight loss since having kids last year.

 

Other performers included: Diddy, Maroon 5 and Sara Bareilles played in Chicago, Cee Lo Green and Lil Wayne hit the stage in L.A. and Gavin DeGraw performed in New Orleans.

Celeb guests at the four events included a slim Mel B, pregnant Kourtney Kardashan, “90210″ star Shenae Grimes, Maria Menounos, a solo Ashlee Simpson and Rosie O’Donnell with fiancee Michelle Rounds.
