We just need to thank Kylie Jenner, because the makeup mogul took to her Instagram Stories to share a few video clips of her daughter, Stormi Webster, playing with cousins North West and Penelope Disick on March 7. Needless to say, these girls are the cutest trio we’ve seen in a while.

In the adorable clips, the trio of girls can be seen holding hands with one another as they walked across one of the Kar-Jenner sisters’ vast green yards. In another vid, Penelope, 7, was spotted holding Stormi, 2, as they walked down the hallway, Nori, 6, speeding in front of them on a mini-bike.

It’s no surprise to see all these cuties playing with each other and having a great time. In fact, we regularly see glimpses of cousin playtime from Khloé KardashianKourtney Kardashian or Kim Kardashian‘s social media pages as well.

But P and Northie are basically a match made in cousin heaven. “North and Penelope call each other sisters, that’s how close they are,” an insider told Life & Style exclusively back in June 2019.

“They want to do everything together. It’s hard to take them anywhere separately,” the source continued. “They call each other on the phone, they beg for playdates most days and they’ll have sleepovers on the weekend.”

The bond that Kim, 39, and Kourt, 40, shared growing up has definitely come back in spades. “They’re always playing dress up and doing each other’s makeup with fake makeup kits that Kim gives them,” the insider dished. “Kris [Jenner] and Kourt and Kim all think it’s so adorable because they really are as close as Kim and Kourt were growing up.”

Plus, their connection is ~music~ to the family’s ears. “North and Penelope want to start a band together, they’re always singing and performing for their parents,” the source gushed. “North is a lot girlier than Penelope who likes to be outside more than in the glam chair like North, but they’re a good balance for each other. They go to school together, but they won’t be able to be in the same class — just like twins aren’t allowed in the same class!”

Clearly, these cousins are going to be BFFs for life.
