Just like Khloe Kardashian, you could say her sister Kourtney has a "revenge body" too.
Ever since her recent split with Scott Disick, the Keeping Up With the Kardashians star has been sharing pics of how she's been relentlessly working out -- and the results are definitely showing!
Check out this black cut-out jumpsuit she wore to little stepsister Kylie Jenner's 18th birthday party on Sunday night.
The mother of three was spotted outside of Nice Guy in Los Angeles, California, where her abs were on full-display in the sexy onesie.

But this wasn't her only revealing weekend look. Kourtney also posed with her sister Kim on Saturday in cleavage-baring body suits.
Not to be outshined by Kourtney and Kim, the birthday girl entered adulthood with a very risqué photo of her own.
Kylie's rumored boyfriend Tyga posted a steamy pic of "the dopest girl ever" to wish her a happy birthday. Not to mention, he also gifted her with a $320,000 Ferrari.
