The 17-year-old reality starlet is known for appearing on "Keeping Up With The Kardashians." She is more famous however, for the Kylie Jenner lip surgery-screaming selfies that she loves to post on her Instagram account.

Netizens have noticed that the Kardashian half-sister's face is changing more and more, especially through the photos that she shared online. The "experts" have also weighed in their opinions.

OK Magazine Australia has talked to a group of specialists who all agreed that she's had Botox, has used lip plumpers and has had a nose job all by the "tender age of 16," according to a report by Hollywood Gossip.

Kylie Jenner's camp has been adamant in denying these claims. Her representative told Mail Online that these Kylie Jenner lip surgery rumors were "so ridiculous and not true."

The Kardashians are not exactly innocent when it comes to plastic surgery rumours. Older sibling Kim Kardashian has had to deal with these claims for a long time now. The public has insisted that she's had surgery on her famously large bottom, her nose and her breasts.

The wife of Kanye West has waved away these rumors, saying that the only surgery she's had is Botox.

Kourtney Kardashian, on the other hand, has been honest about getting breast implants.

On Kylie Jenner's latest Instagram photo however, she moves the focus from her lips to another part of her body, which fueled another round of plastic surgery allegations.

This time, the model and host snapped a selfie highlighting her large butt. The pic shows the reality TV star in front of the mirror posing sideways with her pants down to reveal a tiny bit of underwear.

"Staying comfortable in my @meundies. Time to jump in bed after this long week," was the selfie's caption.

Before being hounded with lip surgery rumors, Kylie Jenner is now facing butt implant allegations. As of press time, however, the Jenner camp has yet to comment about these new plastic surgery claims.
