That’s one hot mama! Kourtney Kardashian flaunted her fit figure in an all-black leather outfit while on a girls’ trip to Las Vegas on Saturday, May 21.

The mother of three, 37, donned a strapless bra top, hot pants and thigh-high boots for her night out at Jewel Nightclub at the Aria Resort & Casino's grand-opening weekend, topping off her look with a thick black choker.

Kourtney, who arrived at the club at 1 a.m., wore her long dark hair down in loose waves and kept her makeup simple and smoky.

“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,” celeb hairstylist Jen Atkins captioned a stunning shot of the reality star.

In Snapchats from the night, Kardashian and her gal pals, including Malika Haqq, can be seen lip-synching along to the songs and giving each other lap dances as they sat at a VIP table and sipped cocktails near the DJ booth. Halsey and the Chainsmokers were also in attendance at the celebration.

Just two days earlier, Kourtney and her sister Kim took their kids — Mason, 6, Penelope, 3, and North, 2 — to the happiest place on Earth: Disneyland. (Baby Reign didn’t seem to partake in the fun.)

There, Penelope and cousin North transformed into tiny pint-size princesses Jasmine and Elsa, respectively. Family pal Ryan Romulus got in on the fun and dressed up as Cinderella.

"They [rode the] Matterhorn," one insider tells Us Weekly of the family group. "Mason was on the ride with a bodyguard, Kourtney was in front."
