Kourtney Kardashian may not be the most interesting sister to look at but tonight she tricked fans into thinking she was her younger sibling when she transformed into Kim Kardashian-West on the season finale of "Keeping Up With The Kardashians." Despite the 40-year-old reality star talking about "boundaries" and stating she needed a break from the show, Kourtney dressed as the 39-year-old KKW Beauty founder and pulled a fast one on her social media followers who mistook her for Kim.

Kourtney Or Kim?!

Posting to Instagram ahead of the finale, Kourtney Kardashian and her sisters showed that they took over different family members' personalities and the mom of three's alter ego was Kim. Posing with Kim's basic bitch ensemble that included a tight black tank top and matching sweats, Kourtney made sure to include oversized neon sunglasses from her sister's recent sunny collaboration with Carolina Lemke. Holding up a nude KKW lipstick the TV personality jokingly hawked her sister's product from her multimillion-dollar beauty line. She also made sure to include Kim's signature selfie and held the phone above her head to give herself the ultimate cleavage.

Fans Are Fooled!

Fans immediately filled up Kourtney Kardashian's comments mistaking the oldest daughter for Kanye West's wife. "Literally thought this was Kim," one fan wrote on her Instagram post. "I thought I was on Kim's Instagram for a minute," wrote another. A third person was fooled too and wrote, "I thought it was Kim for a bit LMAOOO!" Tons of others poked fun at Kourtney and Kim's epic fight earlier this year when the beauty founder dissed her older sister's physical appearance.

Taking It Next Level:

"You're the MOST interesting to look at! Team Kourt," one follower wrote with crying face emojis. "Did you have 7 stylists picking up that outfit for you?" added another. During the "KUWTK" finale, Kourtney impersonated Kim by stating, "my pants are Yeezy, my shoes are Yeezy, I have seven stylists to put me in sweats and leggings." Poking fun at herself she added, "Thank God Kourtney left the table. I can't stand her energy." Kourtney wasn't the only KarJenner impersonating her sisters. Khloé Kardashian acted as momager Kris Jenner, Kendall Jenner was Kylie Jenner, and Kim was Kourtney.
