Mariah Carey combines sexy and festive like no other. The pop diva has been spreading holiday cheer all week, and she gave fans a special gift—a picture of herself "festivating" in sexy lingerie!

The "All I Want for Christmas Is You" singer has been a busy lady this holiday season. She released an amazing music video for her rendition of "Here Comes Santa Claus" a few days ago and partook in an epic Carpool Karaoke session, as well.

On Friday she was back at it again, sharing a super sexy Instagram post of her holiday festivities. In the picture, she kneels in front of the Christmas tree as she sips what appears to be eggnog—while dressed in lingerie, of course. Carey rocks a sparkling black bra, an oversize red flannel shirt, and sparkling black boots as she poses for the sultry snap. Though Mimi's outfit certainly steals the show, her cup is equally festive with its skiing Santa on the stem. Carey captioned the image with, "Festivating, dahlings."

Earlier this week she shared a snap of herself in lingerie while standing in front of a massive tree in her $22 million, $10,000 per night, rental in Aspen, Colo.

There's really no disputing that Carey is the queen of Christmas. The only question left is whether she has more treats in store for her fans before the holiday season ends.
