The stunning Mumma-of-three shared a gorgeous shot of herself in a black one-piece while on a boat in Italy via her lifestyle brands Instagram account, Poosh.
It's safe to say fans were thrilled with this kind of body positivity, taking to the comment section to express their love for Kourtney's new 'no edit' policy.
"Thank you so much for not editing out your stretch marks!! 💓👏🏼", wrote one fan.
"I love when we get to see stretch marks..normal bodies," wrote another.
Another fan gushed: "Oh wow not air brushed. You can actually see her stretch marks and this is what a real body looks like! I love it."
Responding to a fan that questioned her decision to leave her stretch marks untouched, Kourtney wrote: “I love my little stripes.”
YES, MAMA!
Kourtney is currently on vacation in Italy with her three kids, Mason, 9, Penelope, 7, and Reign, 4 which she shares with ex-partner Scott Disick.
We're hoping the stunning star sticks to her unfiltered photo policy from here on!
