Kourtney Kardashian‘s latest photo and video dump shows off the KarJenner family’s Memorial Day Weekend celebrations, as well as the 42-year-old mom’s amazing bikini body! Kourt started the carousel on IG with a low-angled selfie that allowed her fans to see the ample cleavage peaking out of her tiny floral bikini. She gave a pout to the camera and covered her eyes with a pair of black square sunnies.
