Jenner appeared briefly in the special which aired Thursday in the program's opening segment when a singing Buble dropped in on her photo shoot while touring the Universal Studios backlot.
The Keeping Up with the Kardashians star kept things warm with her sexy Santa outfit complete with white fur laced boots and hat while Buble dazzled in a golden tuxedo.
"Tune into NBC tonight at 8 to see the @michaelbuble Christmas special," Jenner wrote on Instagram next to a photo of the two on set next to a Christmas tree.
Mother Kris Jenner shared the selfie moment from the special and also urged fans to tune in on the photo sharing site.
Jenner made headlines in November when her new lip kit sold out in minutes.
