Skin is in! Kourtney Kardashianshowed off her enviable curves in a barely there pair of bikini bottoms via Instagram on Sunday, March 20.

“Sunday funday!” the mother of three captioned the photo, in which she lounges on a gray striped towel out in the sun, her backside barely covered in a black string bikini.

“Double gym selfie,” she captioned the photo, in which both she and Khloé, 31, pull down their workout tights to reveal taut midriffs.

On Friday, the proud mama shared an adorable shot of Penelope waving a wand at a window on a cobblestone street while at Universal Studios’ Wizarding World of Harry Potter.

“A little Harry Potter magic,” she captioned the photo.

Kardashian spent the day at the theme park with ex Scott Disickand their three kids; on Saturday, the family joined others in the Kardashian-Jenner clan for a get-together for Rob ’s birthday.
