Kendall Jenner is said to have gone under the knife after the 18-year-old model/reality-TV star stepped out with a thinner-looking nose. Within just a few months, Jenner's nose seems to have taken on a different shape, which has some leading surgeons saying she may be following in the footsteps of her older half-sister Kim Kardashian (who has a penchant for Botox) and may have gotten cosmetic surgery.

Plastic surgery consultant Miles Berry, from Cosmetic Surgery Partners in London, told the Daily Mail Jenner's nose appears to have been altered. "The bridge of her nose looks a little more crooked in an earlier photo and this could certainly have been smoothed surgically,” he said. “The tip could well be smaller and rather more refined, again pointing to possible surgery.”

But Berry added that since Jenner is so young, she might have undergone a surgery that is less invasive than a rhinoplasty. “An alternative could be that she has had the much less invasive procedure of filler injection and this has smoothed out the bridge,” he explained to the Daily Mail.

“If the bridge is larger and more regular, it will make the tip look better, so this is more probable if there is a short time between pre- and post- images.” He added: “Most surgeons would try to avoid surgery until the patient is a little older, particularly as the face tends to 'fill out' and can change quite noticeably at this age.”

A different doctor, Anthony Youn, agreed with Berry and told Radar Online that it was possible Jenner had cosmetic surgery. “Kim's little sister appears to have a littler nose!” he said. “Kendall looks like she’s undergone some thinning and shortening of her nose, making it more resemble the nose of her famous sister Kim.”

If she did have work done, Youn said, he'd give credit to her doctor. “Her nose looks more elegant and refined. Kudos to her plastic surgeon!”

But that’s not the only thing the “Keeping Up With the Kardashians” star might have done to improve her looks. Licensed aesthetician Alicia Hunter told Radar Online the starlet looked like she might have had lip injections.

“They definitely look like filler, most likely Juvederm,” Hunter said. “Her lips look unnaturally puffy. Unless she just got it done, and there’s swelling, she got too much put in for her age, in my opinion.”

The news about Jenner’s alleged nose job breaks just after middle sister Khloe, 29, told Cosmopolitan UK that when she was 9 she overheard her mother, Kris Jenner, suggest to a family friend that Khloe get a nose job. "I was shocked,” Kardashian told the magazine. “I hadn’t even thought about it.”
