Plenty of KUWTK fans insist that voluptuous figure is thanks to butt implants and a boob job, but Kylie has always insister her figure is all-natural.
Well... most of it, at least. After years of denying she'd had lip filler, the star eventually came clean about that particular cosmetic touch-up.
So has she been keeping any other fillers or surgeries under wraps?
Here’s what we know about Kylie Jenner’s plastic surgery treatments.
The truth about Kylie Jenner’s lip fillers
During a 2015 episode of Keeping Up With the Kardashians, Kylie admits, "I have temporary lip fillers, it's just an insecurity of mine and it's what I wanted to do."

Later in 2017, on an episode of her own reality TV show, Life With Kylie, she talked more openly about her decision to get lip fillers.
“I was 15 and I was insecure about my lips. I have really small lips. And it was like one of my first kisses and a guy was like, ‘I didn’t think you would be a good kisser because you have such small lips’," she said.
"I took that really hard. When a guy you like says that, I don’t know, it just really affected me. I just didn’t feel desirable or pretty.
"I would overline my lips with the lip liner to create the illusion of bigger lips and then, finally, I was like, this lip liner isn't doing it and ended up getting my lips done.”
After her first baby Stormi was born, Kylie shocked everyone with this Instagram photo that showed off a very natural look.
Followers commented on how beautiful she looked and one said, “she looks like the old Kylie here idk why”, to which Kylie herself replied, “I got rid of all my filler”.
That was July 2018, but by October that same year, she was back to her signature plump pout. This time however, she was completely open about her fillers.
In an Instagram story she thanked Pawnta Cosmetic Dermatology of Beverly Hills “for coming through late last night with a lip touch up!” and shared a selfie of herself posing in a white robe with fuller lips.
Ever since she's kept her lips plumped and pouty, suggesting she has no plans to dissolve them again any time soon.
Has she had any other cosmetic procedures done to her face?
According to the beauty mogul herself, the answer is no.
"People think I fully went under the knife and completely reconstructed my face, which is completely false," Jenner told Paper Magazine in 2019.
"I'm terrified! I would never. They don't understand what good hair and makeup and, like, fillers, can really do."
Has Kylie Jenner had a breast augmentation?
In 2015, Kylie Jenner posted an Instagram shot demonstrating a nifty trick she’d shared on her (now shut-down) app to make your boobs look bigger.
And if you're wondering if it was in response to rumours that she’d had breast implants, the answer is probably yes.
"Everyone thinks I've gotten a breast augmentation recently and I haven't. I just use the 'Bombshell' by Victoria's Secret – it's life-changing," she claimed.
"I've gotten all my sisters on it, all my friends and if you ever want the look of bigger breasts, that's what I do."
While she could have very well been telling the truth at the time, we have a sneaky suspicion that she’s had a boob job after she posted this.
The proof is in the pics: clearly she’s not wearing her Victoria’s Secret bra in these photos…
Does Kylie Jenner have butt implants?
Kylie’s figure is the perfect hourglass shape, but that tiny waist is considerably smaller than her breasts and butt, which is why everyone believes she’s had some kind of cosmetic surgery to enhance her derriere.
BBLs are popular among the rich and famous, as are implants and other surgeries to enhance your behind, though Kylie has denied ever getting one herself.
Then again, her figure is a pretty close carbon copy of her big sister Kim Kardashian’s, so you’d be forgiven for thinking it’s just the genes.
But she and Kim are only half-sisters, and Kylie's full-sister Kendall has a very different body type indeed.
So where do Kylie's unreal curves come from? Many believe there's photo evidence that she has, in fact, had butt implants.
When Kylie posted an adorable Instagram pic of her and Stormi, what should have been met with comments like ‘awww’ and ‘so cute’ was overshadowed by what appears to be a scar on her backside, which had everyone insisting she really does have butt implants.
But it's not a scar - it's a tattoo. Kylie has the words 'before sa-nə-tē' tattooed on her upper right butt cheek.
Perhaps this tattoo has been strategically placed to cover something up, some fans mused, and even when Kylie's weight fluctuated through her pregancies, her derriere stayed perfectly round and perky.
Even if this isn't a surgery scar, fans still find it hard to believe the young star hasn't had butt implants.
Her post-baby body
Since having baby Stormi in 2018, Kylie claimed her body changed drastically, saying “My boobs are definitely three times the size, which bothers me. I have stretch marks on my boobs.
"My stomach isn’t the same, my waist isn’t the same, my butt’s bigger, my thighs [are] bigger.”
But before and after photos had fans wondering what the heck she’s talking about because she seemed to look the exact same pre- and post-pregnancy, but we guess you can’t believe everything you see on social media.
Plus, let’s not forget how old the youngest Kardashian-Jenner is still in her 20s, so it’s not too surprising that her body would bounce back so well and quickly after having a baby.
But the same thing happened after Kylie welcomed her second child, a baby boy born in March 2022.
After showing off her bump on Instagram, the reality star seemed to snap right back to her toned pre-baby figure in a matter of weeks and the transformation left fans stunned... and a little suspicious.
With Kylie returning to her pre-baby figure so soon after giving birth, many fans and critics were convinced she must have had some surgical help to get her there, such as liposuction.
But when you consider how much the Kar-Jenner clan spend on beauty treatments, private chefs and trainers, it's possible she may have just had a really, really good workout plan and diet in place.
And we don't expect her body to stop changing any time soon, so keep an eye out for her next transformation.
While we're certain fans will claim it's all surgery, we have a feeling Kylie will keep denying she's had any surgical enhancements.
