Mariah Carey dresses up as Mrs. Claus at sold-out Bangkok concert...

Christmas is coming up. You know what that means? Tis time for Queen of Christmas to get merry! 

Mariah Carey is giving us reason to prepare to sing all parts of her iconic classic 'All I Want For Christmas,' by celebrating Halloween as Mrs. Claus. Mimi belted out the track last night and was certainly feeling exuberant in front of a sold out audience in Bangkok, Thailand! More power to her.
