The "Keeping Up with the Kardashians" star took to Instagram on Sunday, where she showed off her fit physique while wearing a gold halter swimsuit.
Posing on a workout bike, Kourt looked like she was having a lot of fun. The mother-of-three finished her impromptu photo shoot look with a tangerine lip and wore her hair in a slicked-back ponytail.
"In St. Barts #tonight #KUWTK," she captioned the cute candid.
In a second snapshot, the reality star puckered-up for the camera as she flaunted her tight tummy.
Kourt's had no problem showing off her hot bod lately -- just last week, she shared a photo of her bare booty on the social media site.
It's crazy to think that this same time last year the 36-year-old welcomed her third child, baby Reign Aston Disick, with ex-beau Scott Disick. The brunette beauty sure has bounced back, though -- Kourt's never looked better!
