Khloé Kardashian Rubs Her Biological Age In “Livid” Kim Kardashian’s Face: “Me, The Fat One, Is Now Better Than The Best One”

Another day, another Kardashian family competition. This time, Khloé Kardashian is taking the cake as the seventh-slowing aging person in the world — which, as you may guess, only “pissed” off her sister Kim Kardashian.

In The Kardashians Season 5 finale, Khloé, Kim, Kris Jenner and Scott Disick embark on a journey to find out their biological ages. Once they get their TruDiagnostic test results back, Kim learns that she’s biologically almost 10 years younger than her chronological age, while Kris is six years younger than hers.

Hearing the positive news for both her mom and sister only leaves Khloé feeling nervous about her own test results.

“My heart is racing. Like, literally. I feel my pulse beating out of my neck,” Khloé says in her confessional. “If I find out that I’m 812, I’m just gonna cry.”

However, Khloé is pleasantly surprised to learn that her biological age is 28 — which, at the time, was nearly 12 years younger than her actual age.

“Never in a million years — like, if I had to bet money — I never would’ve bet on myself. I would’ve completely lost the bet,” Khloé gushes. “Kim is livid, by the way. Like, I know she’s pissed. I don’t think I’ve ever beat her in anything. Like, what?”

According to the owner of the testing company, Khloé is aging at a pace of 0.72 — and she’s currently No. 7 in the global competition of self-rejuvenation, meaning she’s the seventh-slowest aging person in the world.

“The world needs to know that me, the fat one, is now better than the best one,” Khloé says. “[Kim] was always like, ‘I’m the princess,’ or whatever her tagline was. And my tagline on Keeping Up [With the Kardashians] was, ‘I’m the fat, funny sister,’ if you look at the opening of the show. The fat, funny sister is 12 years younger than her chronological age.”

Kim and Kourtney Kardashian, on the other hand, are not as quick to celebrate the news.

“For sure, I’m pissed. I always want to be the highest achiever,” Kim says, before Kourtney later adds, “It’s so confusing and I don’t believe it. Like, how many people did this test? Like, 10? I want to take it. I’ll be, like, No. 5.”

Despite her sisters’ skepticism, Khloé still manages to block out the haters.

“Jealousy does not look good on you,” she fires back.

The Kardashians is currently streaming on Hulu.
