These might be the cutest little skeletons we've ever seen. Kourtney Kardashian and her kids are getting in the Halloween spirit, and the mother of three took to Instagram yesterday to show off their festive pajamas.

The snap that Kourtney shared features her two oldest children, Mason, 5, and Penelope, 3, lounging in bed with her wearing matching black sweatpants and sweatshirts printed with white skeleton bones. The family's legs and bare feet were entangled as they sat together.

"Skeleton cuddles," the star wrote alongside the sweet 'gram.

But that wasn't the only picture she posted over the weekend. A few hours later, the mom shared a workout selfie that showed off her toned physique, which she captioned: "Working out is one of the only things that helps when I'm feeling anxious."
