ROCKEFELLER CENTER — All we want for Christmas is Mariah.

Pop superstar Mariah Carey joined Santa Claus on stage Tuesday night to perform for the annual Rockefeller Center tree lighting ceremony.

Donning a pair of revealing holiday-themed gowns, the singer belted out tunes in front of a crowd of adoring fans in a pre-recorded concert prior to Wednesday night's official tree lighting.

"Walking to the stage to perform at Rock center," Carey tweeted Tuesday night before the show. "Let the festivities begin! Thx 2 all the lambs who are braving the temps here! LYM!!!"

The 80-foot-tall Norway Spruce will be decked out with 30,000 multicolor LED lights and topped with a 9.5-foot-wide Swarovski crystal during the 80th-annual ceremony, which runs from 7 to 9 p.m. Wednesday.
