Mariah Carey Sings “All I Want For Christmas Is You,” Officially Kicking Off The Holiday Season — VIDEO

I know all of you just took out your cornucopia centerpieces and dusted off your gourd-scented candles and arranged your turkey-shaped accoutrement on your mantles. However, it looks like it is already time to pack up the Thanksgiving decorations and bring out the Glitter DVDs and bottles of Butterfly soda and fur-trimmed red dresses. Oh, haven't you heard? Mariahmas time is here. On Thursday evening, Saks Fifth Avenue in Toronto ushered in their new holiday window display the best way possible: Mariah Carey sang “All I Want For Christmas Is You” for the first time this year at the upscale department store's event. Merry Mariahmas to us all and to all an elusive butterfly chanteuse night.

Much like Punxsutawney Phil and spring, the "Always Be My Baby" diva determines the first day of Mariahmas time; the season begins when Carey delivers her first live rendition of "All I Want For Christmas" of the year. So, thanks to last night's performance in Toronto, Mariahmas 2k16 is here.

Don't be a Mariahmas Scrooge (a Marooge? A Scrariah? A Mimicrooge?), go ahead and get into the spirit of the season now by watching Carey belt out not one, but two holiday songs at Saks' soirée. Lucky for us, the Great and Benevolent Mimi performed her objectively perfect original Christmas tune and "Here Comes Santa Claus" Thursday night. And lucky for us, some people who attended this mini concert were kind enough to record and share the show with the internet.

As far as I am concerned, it is never too early to celebrate Mariahmas. Hey, I'll take it one step further: year-round Mariahmas sounds like a dream. Nay, a sweet, sweet fantasy, baby.
