Kourtney Kardashian set the beach on fire as she showed off her 'hot body' in St. Barts on Thursday, Aug. 20. She opted for a skimpy bandage bikini while enjoying the beach with her half-sister Kendall Jenner, US Magazine reported.

Kourtney, the 36-year-old mother of 3 kids, confidently highlighted the sexy cutouts at her waist and under her cleavage in a yellow and gray two-piece by Agent Provocateur. Her enviable and trim physique were a result of grueling workouts after her high-profile split from Scott Disick, US Magazine noted.

Along with the sexy Kourtney, her half-sister Kendall looked equally gorgeous in a paisley-printed bikini and white eyelet cover-up both by Zimmermann, US Magazine observed. There was a point when Kardashian hilariously took photos of her model sister, 19. Kendall posed expertly with a stick in her hand.

Following her split from Disick, Kendall has been more than comfortable with sharing sexy pics on social media, US Magazine reported. Later that day, Kardashian swapped her bikini with a cleavage-baring gold one-piece. This was featured on her Instagram. Earlier in the week Kourtney had showed off her sizzling body in a palm-printed bandeau top and matching bottoms in yet another bikini photo.

Kourtney's ex Disick has been enjoying his time down in Puerto Vallarta, Mexico. US Weekly confirmed on July 6, Kourtney broke up with her boyfriend of nine years after he was found cosy and close with his ex-girlfriend Chloe Bartoli in the South of France.

Kourtney's decision about the split remains firm till date. They have three kids together - Mason, 5, Penelope, 3, and Reign, 8 months. "Scott texts Kourtney 'I still love you," an insider previously told US Weekly. He added, "And 'I want you so bad' all day and night."
