Thanks to their social media-loving family members, pics of the adorable besties are easy to come by. Here are a few of our absolute faves.
Last Halloween, the cousins were the cutest pair of skunks of Halloween in this pic, which Penelope’s mom, Kourtney Kardashian captioned “#cousinlove.”

The pair love hanging out with their aunt Khloe Kardashian, who looks to be the best babysitter around.
The cute cousins were “best friend ballerinas” celebrating Penelope’s third birthday in July…
...and even got patched up together when they plied a little too hard.
The day after Penelope’s birthday, Kim shared a throwback shot of the pair, with a heartfelt message.
“Happy Birthday P!” Kim wrote. “I know your bday was yesterday but we were celebrating all day! Thanks for being the best big cousin North always looks up to! I love you!”
They even got to meet a “real life” mermaid together in August!
This year, the cousins absolutely crushed the Halloween game with their Elsa and Anna costumes from Frozen.
These two will undoubtedly be besties for life, and we can’t wait to see how many more adorable pics they snap in the process!
