Kourtney Kardashian Rocks a Sexy Leather Two-Piece in Las Vegas -- See the Hot Pics!

Kourtney Kardashian is one hot mama!
The 37-year-old reality star turned heads in a vampy, skin-baring ensemble while attending the third night of the grand opening of the JEWEL nightclub at the ARIA Resort & Casino in Las Vegas on Saturday.
Kourtney showed off her toned tummy in a tiny leather sweetheart bra top. She completed the edgy look with high-waisted leather shorts, thigh-high velvet boots and a chunky choker.

Kardashian later took to Instagram to share a snap of herself inside the club with pals Malika Haqq and Courtenay Semel.
"Vega$," the mother-of-three captioned it.

And it wouldn't be a real night out without documenting the festivities on Snapchat! Kardashian posted a series of videos to the popular app, which showed her mingling in a VIP booth, lip-syncing to tunes with her hair stylist, Jen Atkin, and sticking one dollar bills in her boots, naturally.
On Sunday, Atkin posted a split pic of Kardashian's risqué look to her own Instagram, where she completely gushed over her friend's fit figure in the caption.
"So @kourtneykardash not only took us away for a fun girls night in Vegas but also taught ALL of us girls that you can actually look BETTER after having 3 kids," she wrote.

Earlier this week, Kardashian's daughter, Penelope Disick, was the one having all the fun. The 3-year-old got the full princess treatment while enjoying a play date at Disneyland with her cousin, North West.
