Beverley Hills, California - At midnight on November 1, Mariah Carey officially opened the Christmas season by dropping an iconic video, and ascended her holiday throne.

The Queen of Christmas has spoken.

The pop diva understood the assignment and shared a video declaring the start of the holiday season on Tuesday at 12 AM sharp.

"IT'S TIME!" Carey both wrote on Instagram and sang in a whistle tone riff for the ages.

In the clip, the 52-year-old is first seen cycling on an exercise bike in a black latex bodysuit, striking cat-eye makeup, and a witch's hat.

Behind her, calendar page bats fly through the black-and-white scene, counting down to the end of spooky season, as she lets out a delicious cackle.

When November 1 is reached, the star pulls off a transition for the ages and an instant winter wonderland appears. Mariah dons her famous red Christmas jumpsuit and rides on a plush reindeer.

Of course, to top it all off, Carey's iconic Christmas hit All I Want For Christmas Is You kicks in, declaring it "#MariahSZN."

First released in 1994, the hit is one of the most recognizable and popular holiday tunes of all time. It continues to break records as the first song in history to top the Billboard Hot 100 chart in three separate years, and is the best-selling Christmas album to date. She is currently facing a lawsuit for copyright infringement over a song with the same name.

Last year, Carey released a new Christmas song, Fall in Love At Christmas, together with Khalid and Kirk Franklin.

With her new viral video hit officially kicking off the season, who knows what else the Queen of Christmas will have in store this year.
