Hot Mama Kourtney Kardashian Flaunts Bikini Body with Kendall Jenner in St. Barts

Babe alert!

Kourtney Kardashian showed off her assets in a bikini during her family vacation in St. Bart’s, and she looks absolutely phenomenal.

The newly-single mother of three gallivanted around with her model sis Kendall Jenner, giving the 19-year-old a run for her money.

Kourtney, 36, was wearing an Agent Provocateur yellow and grey bondage bathing suit, flaunting her tone body. She’s been hitting the gym hard in the wake of her split from longtime love Scott Disick, and documenting her efforts on social media.

Sadly, cheating rumors were the final blow to their relationship earlier this summer.

The Kardashians and Jenners are having a blast (and a splash) in St. Bart’s, where they’re also currently filming the upcoming season of Keeping Up with the Kardashians.

Kendall went paddle-boarding with her younger sis’s beau Tyga, and Kylie and Khloé were spotted scuba diving. Kylie and Tyga are no longer making their love a secret, now that she’s 18.

Meanwhile, pregnant Kim stayed in the shade on the yacht with daughter North West. Kourtney and Scott’s children Mason and Penelope were also in tow.
