"Oh okay, so we’re not gonna talk about her leg," wrote one user.
"Photoshop doesn’t count for perfection," another commented.
While out in Los Angeles on Thursday, Kardashian family-friend Jonathan Cheban offered his own opinion on the backlash.
According to Too Fab, Jonathan said "Doesn't matter, she's still hot," and added, "Okay, maybe she took a quarter, a centimeter off, who cares!"
The food blogger also pointed out that it was something that most girls do.
"Every girl, by the way. Every girl," he said.
In addition to this, Cheban scolded Kylie's haters, telling them to "get over it."
"Go get some of your own pictures! Photo -- FaceTune, do something!" he exclaimed.
The former publicist has been best friends with Kim Kardashian for over a decade, often appearing on Keeping Up With The Kardashians.
Having watched Kylie grow up, it's no surprise that he came to the defence of his best friend's sister.
