KIM Kardashian has stunned fans by enlisting Khloe Kardashian and Kris Jenner to take a blood test to learn their biological ages.

During the Season Five finale of Hulu’s The Kardashians, the siblings and their mother underwent a Horvath Test, which is a blood test that tells you how well or poorly you’re aging.

Before getting the results, Khloe, 40, was convinced her family would all score better than her, noting that she has poor eating habits by comparison.

“I honestly feel like all of my sisters would be younger,” she said in a confessional during The Kardashians finale.

She noted that Kourtney Kardashian, in particular, “works out” and “eats great.”

“I love ice cream. cookies and Goldfish. Wheat Thins. Cereal. Love it,” she continued.

Khloe, Kim, 43, Kris, 68, and Scott Disick, 41, gathered together for a video call with the doctor who revealed the results.

First to get their “biological age,” was Kris, whom the doctor said was six years younger than her real age.

Kim went next, with the doctor telling her she’s biologically 34.

The results only made an already-anxious Khloe more worried.

“My heart is racing. I feel my pulse beating out of my neck. Why am I so freaked out? If I find out I’m 812, I’m just gonna cry. I can’t do this,” she said in a confessional.

Khloe learned that her biological age is 28, which she was elated to hear.

She jumped up and down, screaming in excitement.

“Never in a million years! If I had to bet money, I would’ve never bet on myself,” she said in a confessional interview.

“Kim is living, by the way. I know she’s pissed.”

The Skims mogul confirmed that she was, indeed, angry in an interview of her own.

“For sure I’m pissed,” she said.

“I always wanna be the highest achiever.”

Adding insult to injury for Kim, the doctor told Khloe that she’s aging at a pace of .72, making her the seventh slowest-aging person in the world.

“The world need to know that me, the fat one, is now better than the best one,” she said, referring to Kim.

“My tagline on Keeping Up [With the Kardashians] was, ‘I’m the fat funny sister,’ if you look at the opening of the show,” she said.

“The fat funny sister is 12 years older than her chronological age.”

While Khloe admitted she was nervous about the Horvath Test initially, the result completely changed her view.

“This is the best [test] I’ve ever taken in my f**king life. If it’s not broke, don’t fix it,” she joked.

“The kid’s menu coming right up! Pizza!”

She added, “No, I’m not gonna change. And let me tell you, this is not even my prime. Give me a couple years when I’m zen, and let me take this test again.”

AGING GRACEFULLY

While the Horvath test revealed that Kim, Khloe, and Kris are all aging gracefully, the test hasn’t totally alleviated their concerns about getting older.

During an earlier episode of The Kardashians, Kim opened up about her busy schedule and her desire to do more on-camera work.

On The Kardashians, she claimed that she had mapped out a plan for working on TV and film that would allow her to capitalize on her best years.

“I can do a movie a year,” she said in a confessional.

“I’ve got about ten years where I still look good, so that’s all I’ve got in me and then I’ll take some time off.”

QUEEN KRIS

Kris, meanwhile, has been praised as looking more youthful than ever recently.

In June, she shared a video from a photoshoot in London and was praised in the comments as looking younger than Kim.

The Kardashian momager was in the United Kingdom with boyfriend Corey Gamble.

Kris posted photos and videos from the trip on her Instagram feed.

The video showed her smiling as she posed in a hotel room, standing in front of a gold curtain.

She smiled and tilted her head slightly as the camera moved closer to her.

The reality star wore a black velvet blazer with gold details all over.

She had on a full face of makeup and accessorized with a pair of gold earrings.

Kris also shared a few photos that showed her rocking the same look.

The first pic captured her from the waist up, smiling with her head tilted to one side.

A second snap showed Corey, 43, standing next to her in an outfit similar to hers.

His outfit, however, was more gold than black.

Kris had on a silky maxi dress under her ornate blazer and stood with her legs crossed.

She shared outfit details in the caption.

Kris wore a Victoria Beckham dress, Balmain jacket, Judith Leiber bag, and Lorraine Schwartz jewels.

Fans in the comments drooled over the star.

“You are so gorgeous stunning,” one fan gushed.

“Oh my God Kris, stunning,” another wrote.

“That’s the best looking grandmother I have ever seen. You are extremely beautiful and very hot,” a third fan said.

Someone else claimed Kris looked younger than ever.

“Looking younger than Kim,” the fan commented.
