The holiday special featured Teigen and Legend in a sitcom-style format as they prepared for a big family and friend holiday party at their home. The story got periodically interrupted by stunning performances by Legend from his new holiday songs album, A Legendary Christmas.
As Teigen struggled to prepare the holiday meal for the party, she gets a visit from Jenner, her "Fairy God Momager."
"You relax, you are going to love me right now because I have come by to bring you your party favors," Jenner says before getting some branded headbands with the name "Khrissy" on them.
"Everything is better spelled with a K. I mean, Khristmas, Krissy... Merry Khristmas, Khrissy! Get it?" Jenner says.
Jenner later reveals a massive contract from her purpose giving her 45 percent of the profits from their partnership, which Teigen considers a lot.
"Well I didn't give birth to you," Jenner says.
"And I'm officially making you my mother?" Teigen asks.
"That's pretty standard, she tells the camera and smiles," she says.
Fans took to social media to praise, and some to hate on, Jenner's hilarious cameo appearance.

Later in the special, Kardashian is seen talking to Teigen during the party when her cousin interrupts by doing a livestream about how good the parry is on his social media. She introduces Kardashian to the man and then he begins to pitch them ideas for "men makeup."
Teigen and Kardashian run away when Teigen pretends she's going to get her some medicine.
