It's beginning to look and sound a lot like Christmas! The 15th Annual Christmas in Rockefeller Center event will feature two reality show judges, but we doubt they'll be putting up their dukes and battling, since holiday cheer and spirit will be in the air. 

'American Idol' panelist Mariah Carey and 'The Voice' coach Cee Lo Green will be on hand for the TV show, which broadcasts the lighting of the Christmas tree in N.Y.C. It will air Wednesday, Nov. 28 at 8PM EST, so mark your calendars.

We bet we'll hear some of Cee Lo's new tunes off of his holiday album, 'Cee Lo's Magic Moment,' like the crooner's cover of 'Run Rudolph Run.' Of course, Carey is the Christmas queen, and she'll undoubtedly perform her holiday classic 'All I Want for Christmas Is You' among other seasonal tracks.

According to Ace Showbiz, Carey and Green are scheduled to perform alongside a host of other artists, including Il Volo and Victoria Justice. So, it will be a big ol' party in midtown as the 80-foot tall Christmas tree is lit. We'd love to see all these acts throw caution to the wind and do a holiday party jam full of standards and classics of the season.

That what we call star-studded. PopCrushers, who plans to tune into this annual occasion which sparks the Christmas season? There's nothing quite like Christmas in New York City.
