As we now know, Kris Jenner had a role in Ariana Grande's "Thank U, Next" music video, portraying Regina George's mom from Mean Girls, filming Ariana's stage performance. The video as a whole was a much-loved throwback to some classic movies and the filming day was all captured on Keeping Up With The Kardashians.

In the clip from the episode, you can see Ariana meeting Kris in her dressing room after she gets dressed in the all pink tracksuit. Kris complimented Ariana on her lipstick, which was a gift from Kris who came to set with a pack of Kylie's lip kit cosmetics. "She walked in with a Kylie box this big — I literally started crying my eyes out," Ariana said of the gift. 

Later on in the sneak peek of the episode, Ariana advised Kris to do what she feels on set and don't hold back. "This is the first time that I’ve ever been in a professional music video with an iconic artist and someone I admire very much," Kris said in the confessional. "I don’t want to let Ariana down. No, no, no."
