The Kardashians star's videos show an excited North, along with Penelope and another friend, on stage with Perry as the singer gushes over the pre-teen's TikTok page.

"So the reason I know your name is because I'm a huge fan of your TikTok," the Dark Horse artist is heard telling North in the clip.

"I've seen a couple of them that you've made. You're a really good dancer, and I thought what better way to be a great dancer than to show the world your awesome dance moves?"

Of course, the proud mom perfectly captured her daughter's first stage appearance as she was seated front and center.

Perry then gifted North and her crew a chance to show off their moves and do a cartwheel during the "walk-off competition."

The group also busted out some dance moves alongside the singer's dancers.

Once again, North has proven that she truly is a star in the making!
