Kourtney Kardashian flaunted her killer "revenge body" in a sexy new snap on Instagram, People reported. The "Keeping Up With The Kardashians" star posed in a sexy silver string bikini while riding a tricycle, showing her ex Scott Disick exactly what he's missing out on since the couple split in July.

The 36-year-old reality star wore silver rouched bikini bottoms and a sexy silver bikini top with a pair of black sunglasses and her long, dark hair loose and straight. She rode a yellow tricycle barefoot as she smiled for the camera.

"Happy Labor Day! wait, there's no emoji for a tricycle with no handles?! by @joycebonelli," she captioned the photo.

Kardashian has been posting a number of sexy photos on her Instagram ever since the split from her longtime boyfriend Disick in July, the Daily Mail reported. She's also been working hard at slimming down to her pre-baby figure after giving birth to her third child, Reign Aston Disick, last December.

She shares three children with Disick, including 9-month-old Reign, 3-year-old Penelope Scotland Disick and 5-year-old Mason Dash Disick. Kardashian and Disick dated for nine years before they called it quits.

Despite the couple's on-and-off past, it looks like they're broken up for good this time. Disick was recently spotted visiting Kardashian's home in Calabasas, Calif., TMZ reported. But instead of driving through on the right, Disick had to line up on the left side near the guard's shack, entering his former home as a visitor.
