Kourtney Kardashian’s Toned Abs Lead This Weekend’s Hottest Star Sightings

Kourtney Kardashian’s abs are ridiculous.

The Keeping Up with the Kardashians star showed off her toned stomach in a bondage-inspired leather bralette and shorts, while attending the Jewel nightclub opening at the Aria Resort & Casino in Las Vegas, Nev. on Saturday (May 21, 2016). It’s very safe to say that she’s never looked hotter.

The 37-year-old enjoyed some well-deserved time off from mommy duties to spend the night partying with friends Malika Haqq and Jen Atkin. She also documented her night on Snapchat, which included them lip syncing and giving each other lap dances.
