Dressed in a similar pink velour track suit and holding up a camcorder, Jenner excitingly gets out of her seat as Grande and the rest of The Plastics perform a sexy Christmas-inspired version of the song. Fans online went nuts for her appearance, with Jenner's famous "You're doing amazing, sweetie" meme being compared to her new cameo.
Truly one of the stars of the entire music video, a big moment for Jenner comes at the end where she's sitting in her seat and yells, "Thank you, next. B**ch!"
Jenner is just one of many celebrities who make an appearance in the highly anticipated Grande clip, and the singer epically channels various characters from girl power movies, aside from Mean Girls, such as Torrance Shipman in Bring It On, Elle Woods in Legally Blonde and Jenna Rink in 13 Going on 30.
