North West and Penelope Disick were born to be besties.
Sure, theyโre relatedโฆ But thereโs no rule that says you have to get along with your fam!
And yet these two have been inseparable since forever.
Clearly, the cute cousins have modelled their close-as-sisters relationship on their mamas, Kim and Kourtney Kardashian.
And Kim knows how precious their bond is.
โThanks for being the best big cousin North always looks up to!โ the reality star posted in a message to Pene on Instagram. โI love you!โ
Because we love all things #girlpower (and, you know, out-of-control adorable), weโve pulled together some of P and Noriโs sweetest BFF moments over the years. Click through to check out their super-sweet snaps!
