So what is Kim Kardashian's biological age? Reality star 'livid' by results as family share details of DNA tests… and Kris Jenner is furious too

Most of The Kardashians learned what their 'biological age' is on the Season 5 finale of Hulu series, and not everyone was happy.

During the start of the episode, Kim told Khloe Kardashian and Kris Jenner about a test that reveals how old your actual body is, compared to your physical age.

Kim - who recently started her therapy journey -  Kris, Khloe and Scott Disick all took the test, with everyone but Scott getting results less of what their actual age is.

Much to everyone's surprise, Khloe was the big winner, with her biological age turning out to be 28, 11 years younger than her then-age of 39.

Kim's biological age was 34, a nine and a half-year difference, while Kris was six years younger, though she still thought it would be much less.

Kim adds in confession, ‘So we are getting our results today and we have the owner of the company calling us to walk through our results. I am so nervous and I’ve never been more excited for something in my life.’

They connect on a video call with Matt Dawson, MD, CEO of TruDiagnostic, as Kim says, ‘We are so excited to hear our results.’

Matt says, ‘Kris, when I look at your results, the first thing we’ll talk about is your biologic age. So you are six years younger than your chronologic age,’ as Khloe cheers and claps.

‘Oh good, thank you, I’ll take it,’ Kris says with a smile that doesn’t look entirely genuine, as Kim admits in confession, ‘She’s pissed. She thought she was gonna be, for sure, my age, like for sure, for sure.’

Matt asks, ‘Kim, are you ready for yours?’ Kim says, ‘I hope I’m younger, am I younger? Before I open it? Just tell me, am I younger?’

Matt reveals, ‘You’re younger, so you should give yourself a pat on the back,’ as Kim opens the packet and exclaims, ‘I’m 34! Yes! That’s almost 10 years younger!’ The rest of the family is stunned but Scott says, ‘That makes sense.’

Matt adds, ‘It’s incredible. I mean, that is a really amazing score, and I think the more impressive thing, Kim, than just the age, is the pace of aging. 0.82 means you’re aging 18% slower than most people your age, that’s why you’re nine years younger,’ as Khloe says, ‘Oh this is f***ing amazing.’

Kim adds in confession, ‘I’m happy. I’m so happy. You know, it’s nine and a half years, I think, so 10 years, let’s round it off. I’m 10 years younger. I feel like it, I act like it, I look like it.’

Dr. Matt continues, ‘So your diet is on point, so your A1C is related to how much sugar…’ as Khloe admits she has ‘anxiety’ about the results.

Kris says in confession, ‘Khloe is so nervous about these results from this test that she’s making me nervous, so I just want a good result for her.’

As Dr. Matt continues, Khloe’s anxious ramblings continue, as Kim says in confession, ‘If it comes out that she’s older than she is, I think she’d leave, like, very pissed off, I think she would just like storm out.’

Kim tells Matt, ‘OK, I feel so young. Should I pass it on to my “younger sister” or my “older sister”?’ as Kris laughs.

Matt says Khloe is next, as Khloe says, ‘I’m nervous because like the pressure of you being 34,’ as she adds in confession, ‘My heart is racing, like literally, like I feel my pulse beating out of my neck, I’m like, what the f**k? Like why am I this freaked out? I don’t know why. I don’t know what this like what this is going to do for me, but if I find out I’m like eight-hundred-and-twelve I’m just gonna cry, like I can’t do this.’

Dr. Matt says, ‘I’ve told your mother and your sister that they are world-class agers. You are a world champion,’ as Kim opens the packet and screams, ‘Khloe! You’re in your 20s!’

‘SHUT UP! WOW!’ Khloe screams as they show landmarks from Los Angeles and Las Vegas and New York and London and Paris and Australia and Antarctica and other remote locales, with Khloe’s screaming still continuing.

Back in the room she practically collapses behind the couch as Kris jokes, ‘I lost my hearing,’ and Scott says, ‘You’re a child,’ as Kim reveals, ‘She is 28 years old.’

Khloe asks, ‘Can you sign this with like your PhD or whatever you have that I can frame it?’ as she continues freaking out.

Khloe says in confession, ‘Never in a million years… like if I had to bet money, I never would have bet on myself. I would have completely lost the bet. Kim is livid, by the way, like I know she’s pissed.’

Kim admits in confession, ‘For sure I’m pissed. I always want to be the highest achiever,’ as Khloe adds in her confession, ‘I don’t think I’ve ever beat her in anything, like what?’

Khloe screams, ‘SHUT UP EVERYONE,’ even though no one was saying anything before telling Dr. Matt, ‘Sorry, sir,’ as he says, ‘I mean, this is exciting news for you, it is. Your pace of aging is 0.72,’ which stuns both Kim and Khloe.

‘There is a global competition on self-rejuvenation, and right now you would be number seven in the world,’ Dr. Matt tells them, which stuns them all.

‘You’re number seven in the world in the rejuvenation Olympics,’ Kim tells Khloe, who runs around the couch and says, ‘I’ve never won anything,’ as she asks him to repeat all that.

Khloe says in confession, ‘The world needs to know that me, the fat one, is now better than the best one. She was always like, “I’m the princess,” or whatever her tagline was,’ referring to the family’s original E! TV series Keeping Up With the Kardashians.

‘And my tagline on Keeping Up was, “I’m the fat funny sister,” if you look at the opening of the show,’ Khloe says in confession.

Khloe asks, ‘Can you sign this with like your PhD or whatever you have that I can frame it?’ as she continues freaking out

Khloe tells Dr. Matt, ‘I think you are the best man I’ve met in a long time, I’m very happy with this,’ as Scott jokes, ‘That doesn’t say much.’

Khloe continues in confession, ‘The fat funny sister is 12 years younger than her chronological age.’

Khloe walks around the couch to Scott, saying she’s going to hold his hand as Dr. Matt says, ‘You look a little nervous.’

Scott responds, ‘Well, you know, I mean, the competition is tough,’ as Dr. Matt says, ‘I’ll tell you, your biologic is the same as your calendar age. Usually what that means is, probably in your past, you probably not focused on health as much.’

Scott admits, ‘Yeah, there was probably 10, 15 years there where I was… going pretty heavy into…’ as they say, ‘Drugs,’ as Scott says, ‘Drugs, yeah, thanks,’ and Kim says, ‘Drugs and alcohol.’

‘Yeah, drugs and alcohol were a big big…’ as Khloe continues, ‘Strippers, prostitutes,’ as Scott says, ‘Strippers were involved, prostitutes, not really.’

Scott adds, ‘15 years of really beating myself down,’ as Khloe says, ‘That’s fantastic, because we didn’t really know where this was gonna go for Scott.’

Scott admits, ‘Yeah, I thought it was gonna be real bad,’ as Khloe says, ‘This was actually the coolest thing we’ve ever done.’

Khloe admits in confession, ‘I hated this test in the beginning. This is the best test I’ve ever taken in my f***ing life. If it’s not broke, don’t fix it. The kids menu? Coming right up. Pizza? Like why? No I’m not going to change. And let me tell you. This is not even my prime. I’ve been in way better shape than this. I haven’t slept, I’m stressed the f**k out!’

Khloe walks around the couch to Scott, saying she’s going to hold his hand as Dr. Matt says, ‘You look a little nervous'

Kim admits in confession, ‘Khloe wins on this one, guys. Khloe is 28 years old. Good for her, and… I gotta get down.’

Khloe adds, ‘Give me a couple of years, when I’m zen, let me take this test again.’

Kim tells her family, ‘I’m gonna re-do this every six months and if I don’t get younger and younger every single time…’

Kim says in confession, ‘S**t, now I’ve gotta do what she’s doing,’ as Khloe says in confession, ‘Milkshakes! Oreo milkshakes, in particular.’

They thank the doctor and end the call as Kris says, ‘Khloe, you are such a rock star, as she says, ‘I think the kids menu gets me this far,’ as Kim is still stunned.
