Khloe Kardashian Trolls People Who Confuse Her With Sister Kourtney

Khloe Kardashian is so over being mistaken for her sister. The Good American founder, 38, took to her Instagram Stories this week to offer a hilariously helpful (and sarcastic) tutorial for people who can't tell her apart from Kourtney Kardashian. Voicing her frustration, Khloe declared that she and Kourtney, 44, are called by each other's names "on a daily basis multiple times a day."

"Hey, so for those who can't tell me and @kourtneykardash apart, this is for you," she began her slideshow. "I totally understand how we look like identical twins, so this might be challenging for some, but hopefully, this presentation will help. Especially to the people that were screaming 'Kourtney Kourtney' as I walked by... this one's got you."

Sharing a photo of Kourtney with short dark hair, the Kardashians star wrote: "This is my sister Kourtney. She's pretty fabulous, gorgeous, hysterical... So I get how people mix us up. A few ways to tell us apart is that 99% of the time [Kourtney] is a brunette, whereas I am 99% of the time a blonde."

Showing another photo of Mrs. Barker, Khloe joked, "I get it she is hot as f---... Again, maybe this is where people keep blending us together because we are f---ing identical in the way we look." Khloe then goes on to reference the huge "dead giveaway" difference in height between the two: Kourtney is just five-feet-one-inch tall, while Khloe stands at five-feet-ten-inches. To illustrate her point, she shared a photo lineup of all five Kardashian-Jenner sisters in height order. The mother of two then shared a photo of herself, once again pointing out that she is the tall, blonde one, adding that she's got lighter eyes.

She also referenced Kourtney's Las Vegas wedding with Travis Barker, in which the Elvis Presley impersonator who married them mistakenly called the bride by the wrong name. "This happens to us on a daily basis multiple times a day," she added. "I'm being conservative by saying a daily basis."

For good measure, Khloe shared an image of the cover art for the 1988 Arnold Schwarzenegger-Danny DeVito comedy, Twins, noting the tagline: "Only their mother can tell them apart." She shared a side-by-side photo next with Kourtney, wearing a nearly identical outfit. the same line alongside a side-by-side photo with Kourtney, in which -- aside from wearing a nearly identical outfit -- the sisters could not possibly look more different.
