Mariah Carey is joining forces with New York City to celebrate the milestone of her holiday hit "All I Want for Christmas Is You."
It's the 25th anniversary of her album "Merry Christmas" and the single "All I Want for Christmas Is You" has hit the number one spot of the Billboard Hot 100 chart for the first time!
Mariah stopped by the Empire State Building last night to flip the switch to the top of the skyscraper for a new music-to-light show. The lights of the skyscraper will correspond with the notes of the song which will play simultaneously on iHeartMedia New York's Z100, Power 105.1, 103.5 KTU and 106.7 Lite FM starting at 8 p.m. from Thursday through Christmas Day.
Mariah is debuting a new video of "All I Want For Christmas Is You" tomorrow on YouTube
