Kourtney was, in fact, snapping, posting a video of herself walking barefoot in her all-white pajamas. And the mother of three has really embraced the all-white theme. On both Tuesday and Wednesday, she rocked a sexy white bikini in photos with her young son, Reign.

She captioned the pics, “Tuesdaze” and “Wednesdaze.”

Kourt also showed off her bangin’ bod in a full-length bikini mirror selfie, writing, “Short girl problems.”

Kardashian has been working hard at the gym to keep her svelte figure, and it’s clearly paying off!

While the former couple haven’t posed for any pics together, Disick did snap a selfie for Instagram, writing, “On that white picket fence s**t.”

It’s been more than a year since the pair ended their almost decade-long relationship. Since then, they have managed to remain amicable and Disick has come on several of the Kardashian family vacations.
