Fans are becoming less and less convinced that Kendall Jenner hasn’t had any plastic surgery.

In a selfie shared on her Instagram account this week, the 21-year-old showed off her bangin’ bikini bod — and revealed that she does possess some of the curves her famous Kardashian sisters are known for.

It didn’t take long for users to point out that the model appears to be rocking larger hips, with one page posting a side-by-side comparison of the brunette’s figure now vs. a few years ago. “Natural sista my ass,” an account with the handle @wecannotkuwtk_ captioned the split.

“She WAS natural like the others, now she is FAKE like the others,” one commenter wrote, while someone else said, “Omg lol she’s so fake.” Another added, “That belly button looks suspicious,” insinuating that the image had been Photoshopped.

But a few fans stood up for the reality star, with one person writing, “That’s just the bikini effect… because it’s higher,” while another reasoned, “She’s leaning against a couch.”

Kendall recently spoke out on her app about rumors that she’s had work done, admitting, “It’s all so exhausting.” And reports of her going under the knife only intensified after she let younger sister Kylie Jenner do her makeup for a livestream chat.

“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!’ I was like, ‘This is CRAZY,’” she recalled.

Unfortunately, the Victoria’s Secret beauty is no stranger to criticism. “I found this Instagram page devoted to Kardashian bashing and it has a lot of followers,” she shared. “It was upsetting for me to look at because this person dedicated an entire page to just dissing the whole family and being like, ‘These people suck.’”
