Kim Kardashian Shares the Sweetest Bedtime Photo of North and Penelope

North West and her cousin Penelope Disick really are the cutest BFFs around! North's mom, Kim Kardashian, took to Instagram on Thursday night to share a precious photo of the pair getting ready for bed. In the snapshot, North and Penelope appear to have just gotten out of the bath and are wrapped up in towels. North is seen sweetly reaching over to stroke her cousin's hair. "Night night," Kim wrote alongside angel emoji. Of course, this isn't the first time we've seen these two playmates being cute with each other. In October, Kim shared a photo of the two trick-or-treating, and in September, we got a glimpse of their fun car ride with Penelope's older brother, Mason. See their latest snap above, then check out more of their cutest moments together.
