Mariah Carey - All I Want For Christmas Is You - Christmas in Rockefeller Center 2013 - Video

Mariah Carey sang "All I Want For Christmas Is You" on Christmas in Rockefeller Center.

This is Mariah's signature Christmas song!

She's been very busy since quitting as judge of American Idol this year. I am however very grateful that she helped discover Candice Glover, Idol's current superstar and heir to Mariah's pop diva throne.

This is Mariah's season really. She's just so festive.
