The diva also released a new website and shared an adorable home video of her son rocking out in the kitchen.

Mariah Carey is becoming quite the Mrs. Claus, heaping gifts on her fans in the holiday season she's helped soundtrack for two decades.

On Thursday (Dec. 22), the Queen of Christmas released both a music video for the classic song "Here Comes Santa Claus" and launched a new website, MariahsWorld.com, to share all of her favorite things on the Internet. 

The singer has also promised to release two more new videos for "O Holy Night" and "Joy to the World" on Friday and Saturday, making the lead-up to Christmas extra merry and bright. 

Check out "Here Comes Santa Claus" and a preview for all three videos here:

As what may be the star on the Christmas tree, the diva also delivered a peek into her kitchen, tweeting a video of herself and her 5-year-old son dancing and singing along to her holiday classic "All I Want for Christmas Is You." As Carey stirs a pot of tomato sauce on the stove, her son Moroccan is completely adorable getting down to his mom's song.
