Mariah Carey has brought joy to the world year after year with her undeniable Christmas cheer through song. This year was no different as the 'Merry Christmas II You' creator commanded the stage at Disney's Magic Kingdom.

Carey, who recently confirmed she and husband Nick Cannon were expecting twins, performed her classic yuletide tunes during 'Disney Parks Christmas Day Parade' TV Special. Surrounded by cheerful cheerleaders, elegant ballerinas and Santa himself, the songstress sang her hit 'All I Want For Christmas Is You' and her new holiday smash 'Oh Santa,' which has landed at No. 1 on the Billboard charts.
