(CNN) Try to read this story and not hear the song in your head.

Too late.

If you aren't hearing "All I Want For Christmas Is You" by Mariah Carey in your mind, you shall soon hear it everywhere else.

The song celebrates its 25th anniversary this year, and even Carey is excited.

Early Friday she posted a video on her official Instagram account of her in bed at 11:59 p.m. wearing her Halloween outfit.
