Earlier this week, Keeping Up With The Kardashians fans were left devastated after it was announced the popular US sitcom is coming to an end.

The very first episode of the popular E! reality show aired back in 2007, and the Kardashian-Jenner clan have come such a long way since the first series.

Looking back at the first episode, The Kardashians were living a relatively normal life in Los Angeles.

Now, 18 seasons later, global stars Kim Kardashian, Kourtney, Khloe, Kendall Jenner and Kylie are virtually unrecognisable from the fresh-faced sisters who first appeared on the show all those years ago.

The Kardashians and Jenners have changed a lot over the years

From their sizzling good looks, gym-toned bodies and designer outfits, their success has certainly given them the chance to try many different styles and trends.

The sisters have admitted to some procedures and denied some claims made by fans and viewers of different surgeries.

Kylie Jenner

Kylie has admitted to using lip fillers

Kylie, 23, is the youngest sibling of the famous sisters, and was just a teenager when she used fillers after feeling insecure about her lips.

She explained why she turned to the procedure on Life Of Kylie, saying: "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.' But I took that really hard."

The makeup mogul looked a lot different in the past

In 2015 she owned up to having lip fillers, saying: "I have temporary lip fillers, it's just an insecurity of mine and it's what I wanted to do.

"I want to admit to the lips, but people are so quick to judge me on everything, so I might have tiptoed around the truth. But I didn't lie."

Kylie has always insisted she's not had any other surgery.

Kendall Jenner

Kendall Jenner is known for her model looks

Stunning 24-year-old supermodel Kendall Jenner has repeatedly denied having any facial surgery.

Back in 2017, there was a rumour that Kendall had deleted her Instagram account in November because she underwent full facial reconstruction surgery.

However, Kendall denied the claims, writing on Instagram at the time: :When I deleted my Instagram back in November, people were saying, 'Kendall deleted her account to have full facial reconstruction!'

"I think they might have been referencing the day Kylie and I did a livestream for our book.

The star denied she underwent full facial reconstruction surgery

"We had to hurry, so I let Ky do my face. I never wear lip liner or lipstick unless it’s the occasional obvious red.

"I left all of the makeup on because we were so rushed and I went out and did my thing. I LOVED my makeup. I never say this, but I just felt so pretty."

She added: "All of a sudden, photos of us came out with headlines like, 'OMG Kendall got her lips done and got full facial reconstruction—look at her cheekbones, look at her nose!'

"Kylie saw it all unfold and felt bad, so she went on Snapchat and took the blame.

"It’s all so exhausting. As a model, why would I have my face reconstructed? It doesn’t even make sense. It’s crazy because sometimes I feel like people just want me to lose."

Khloe Kardashian

Khloe has admitted she's a fan of cosmetic surgery in the past

Khloe has admitted she's a fan of cosmetic surgery in the past - comparing it to "putting on a bit of makeup".

She told Cosmopolitan back in March 2016: "There's this misconception that I'm not into plastic surgery, but I'm into it and I don't care if you have it.

"We're all putting on a f***ing mask basically every day anyway.

"When you dye your hair, you're changing who you are, and I don't think there's anything wrong with that."

She also admitted to using fillers, but said she didn't like it.

The reality star explained once: "[Fillers] did not work for me. I looked crazy, and I still think the effects are in there. I went to have it all dissolved like three times.

She once admitted to using fillers, but said she didn't like it

"My face was so f***ed I had to go and get this whole thing dissolved. It was a bummer and now I'm afraid to do it again. And I’m almost like, I swear things are still in my face."

Khloe also recently poked fun at surgery rumours, joking her unrecognisable looks were a result of her "weekly face transplant".

This came as one fan asked her online: "Why do you look so different in all your photos?"

Getting sassy, Khloe replied: "From my weekly face transplant clearly."

Kim Kardashian

Kim has denied ever having a nose job

Kim looks drastically different since the start of KUWTK, with the bombshell regularly sharing scorching snaps to social media.

The mum-of-four has said she underwent a hair removal procedure that lifted her face.

She told People magazine: "I lasered my baby hairs off years ago, because my forehead had all these little baby hairs, and I would always break out because of them."

Kim has remained secretive over any other surgeries she may have had, but has denied ever having a nose job.

She told makeup expert Mario Dedivanovic in 2019: "“I never had my nose done.

"Everyone thought I did, and I said wait until I have kids because your real features come out."

She has admitted she loves a bit of botox, which she says, "isn't plastic surgery."

Kourtney Kardashian

Kourtney had a boob job before KUWTK began

Kourtney had a boob job when she was in college, but revealed she regretted it and wanted her implants removed.

She said during the early KUWTK days: "I had my boobs done but if I could go back, I wouldn't have done it. I was so cute before."

These days Kourtney, 41, is known for trying to stay young through her diet.

The global star admitted she regretted having her boob job

The star long endorsed an organic, dairy-free keto diet that almost completely cuts out artificial products in favour of natural ingredients.

She even makes sure her children Penelope, Mason and Reign eat organic almost all the time.

When it comes to deserts, she'll indulge in organic offerings like matcha chia seed pudding.
