on Tuesday night to share a photo from the night of the awards show, as she posed in front of a blank wall.

The mother-of-three finished off the look with a pair of black sunglasses, a silver clutch, and black pumps.
The E! star captioned her post: "You know she’s a real best friend when you can’t find an outfit for the Grammy’s and she lends you one straight from her closet, straight from the runway, that she hasn’t even worn yet. 🥺🥺🥺 👰🏻♀️🖤."
FAN BACKLASH
Although Kourtney credited her long-time friend for her flawless appearance, fans were not so convinced.
Several took to the comments section to for over-editing the pictures, as they claimed she didn't appear that way in person.
"What’s with the weird face and lips?" one asked.
"Sis what’s wrong with your lips," a second agreed.
A third ranted: "HER FACE DOESN’T REALLY LOOK LIKE THAT."
"1st pic- when you move too fast and the filter gives you two sets of eyebrows? Sorry. She's absolutely beautiful but that's all I see in the 1st pic," another claimed.
"What happened to your face," a fifth inquired.
NATURAL BEAUTY
Kourtney's backlash followed her rare unedited video as a clap back to fans who believe she's had serious work done.
Earlier this month, the TV star showed off her glowing skin as she laid back in a white bathrobe.
The California native swept her hair back into a tousled updo and appeared not to have a scrap of makeup on her face.
Kourtney shared a close-up of her skin while pulling silly faces at the camera in a brief video on her Instagram Stories.
Tagging her favorite beauty treatment, she captioned it: "A little toast for my sandwich @thebeautysandwich."
The Hulu star has been sharing more bare-faced videos since she was accused of getting cosmetic work.
KEEPING IT REAL
Kourtney also shut down claims that she's had an "eyebrow lift", insisting her wide-eyed look was simply down to the facial.
Filming herself getting laser treatment on her face, she told fans: "Hi guys, I am doing some... what is this?"
"Some beauty sandwich," the technician replied.
Kourtney went on: "So for all of you who thought that I got an eyebrow lift on my recent Instagram post video it is actually just a beauty sandwich."
KOURT'S CLAP BACK
Back in December, the reality star faced claims she'd had a nose job and Botox.
A since-deleted Instagram account under the name "popcultureangel" uploaded a series of throwback images of Kourtney with Khloe and Kim.
The account captioned the photos: "The kardashians before they became 'the Kardashians.'"
After one fan said Kourtney is the "only one who really didn't change," another user claimed the oldest Kardashian sister has had work done.
"Kourtney got plenty of surgery!" the person wrote.
"She just did it in an extremely natural way that still complimented her features instead of changed them.
"Botox, nose job, some sort of butt shot or BBL just to start."
The busy mom quickly clapped back at the claim, writing: "No better compliment than a too good to be real kind of compliment.
"Butt shot and Brazilian butt lift, um thanks. And you were just getting started."
