The 10-year-old son of Kourtney Kardashian and Scott Disick made an appearance in one of TikTok star Addison Rae’s videos this weekend.

The pair did a viral dance challenge to the song “100 Racks” by Quality Control and Offset.

Kourt also got in on the fun. The mom of three, 41, and the social media star, 19, donned matching Kids See Ghosts sweatshirts made by Kanye West for a “besties” dance to Playboi Carti’s “Shoota.”

They also joked around and acted out a scene using audio of a Khloé Kardashian and Kris Jenner fight.

Rae is a member of the TikTok collective the Hype House, a group of popular creators who produce content and live together. She has 47.2 million followers on the app.

Despite his family’s celebrity status, the oldest Disick child is starstruck by online creators. In March, he created an Instagram account without his parents’ permission, which was later deleted, and talked about his love of TikTok.

“Will there be Hype House editions? For mine, no. We don’t really do those,” Disick told Instagram commenters about his TikTok videos, which were also deleted. When a commenter said that Rae is not a celebrity, Disick was quick to jump to her defense. “Yes, she is,” he said. “Well, she’s a TikToker but now she’s basically a celebrity from it.”

It’s not clear when the videos were filmed: Rae and the Kardashians live in LA, but the reality-TV brood has been holed up at West’s ranch in Wyoming since last week.

This isn’t the first time a Kardashian sister indulged their Gen Z spawn. In March 2019, Kourt’s sister Kim brought her oldest daughter, North, then 5, to JoJo Siwa’s house for a playdate. The outing was featured on both Siwa’s YouTube channel and on E’s “Keeping Up With the Kardashians.”
