On Thursday, the 46-year-old singer Instagrammed a squeal-worthy video of her and her son, 5-year-old Moroccan, dancing around the kitchen to her classic hit, "All I Want for Christmas Is You." Clad in their pajamas -- Mariah's choice being a sexy red nightie and robe, of course -- the two definitely make a pretty adorable duo.
Mariah also impressively multitasks barefoot in the kitchen, cooking up her sauce while mugging for the camera and enjoying a precious moment with her son. There was no sign of Moroccan's twin sister, Monroe, though Mariah does give her daughter a shout-out.
The legendary diva is spending the holidays in Aspen, Colorado, with her children, as well as boyfriend Bryan Tanaka. Earlier this week, an eyewitness told ET that the couple hasn't been shy about showing lots of PDA.
"They walk around holding each other's hands and are always very affectionate. [They're] always smooching," the eyewitness said, adding that the couple, who are "clearly boyfriend and girlfriend" get along great and "like to cuddle."
Another source told ET that Mariah's ex-husband, Nick Cannon, will be joining the group.
"As he normally does for the holidays, Nick Cannon will be joining Carey, Tanaka and the kids in Aspen later this week," the source said.
But Mariah's break won't last too long -- she's set to perform on ABC's Dick Clark's New Year's Rockin' Eve With Ryan Seacrest in New York City on New Year's Eve.
