The Wild 'n Out host donned a red suit, fake belly, a white beard and a Santa hat and posed for some precious snapshots with "Dem Babies" in Aspen.
"Best presents anyone could ask for! #Dembabies#RocandRoe," the 32-year-old singer captioned one lovely black-and-white snapshot.
The proud papa is wrapping his arms around his cute kids in front of the family's tree. Monroe looks sweet in her party dress, while her brother is more casual in a pair of festive pajamas.
In another sweet pic, Cannon poses for a selfie with his little boy and adds "Santa is tired but we still going! #KidsDontHaveAnOffButton#IWishIDrank#Festive#SantaSuitHotAsHell#MerryChristmas."
The pop superstar, clad in a red dress, smiled with her "favorite lil Santa" in a delightful pic.
How cute is Moroccan's round belly?!
The Grammy winner also wished her fans a "Merry Christmas" along with a wonderful snapshot with her hubby. The couple is grinning widely for the camera, and Cannon's beard is lowered around his neck so we can see his whole glowing face. He is also holding a large present, perhaps for Mariah?
Looks like the family enjoyed a wonderful holiday celebration!
