Kim Kardashian's Butt has been a big topic lately. Criticism of the "Keeping Up With The Kardashians" star's backside has been in full force ever since a few unretouched vacation photos of Kim K. wearing a bikini made rounds. Even Piers Morgan decided to take aim at Kim Kardashian's butt in an attempt to make fun of the reality star. Now it looks like there are even a few plastic surgeons weighing in on Kim's butt, claiming that the "KUWTK" went too far with plastic surgery to enhance her features.

Is Kim's butt real or is it fake?

Kim Kardashian has always argued that her butt is real and not the result of a skillful plastic surgeon.

Not true claims Dr. Aardon Rollins of Elite Body Sculptures. He says the leaked Kim Kardashian booty pictures should be a warning to those who want a big fake booty via a procedure called a Brazilian butt lift. Dr. Rollins says that the recent Kim K. booty pictures show what can happen when a butt lift goes all wrong.

Dr. Rollins talked about Kim Kardashian's butt and said that those wanting a Brazilian butt lift or fat transfers should consider what could go wrong. If they had cellulite before the procedure, they will have cellulite afterward as well. He also said that "problem fat" stays a problem no matter what part of the fat is removed from or transferred to.

Based on the unretouched pictures of Kim Kardashian's butt [VIDEO], the plastic surgeon warned of another issue that he says is a clue as to whether she's had work done on her butt in the past. After having children and gaining and losing weight, the doctor said it's like blowing up a balloon and deflating it over and over again. Which explains why Kim Kardashian's butt looks like a deflated balloon in the new photos.

Kylie Jenner's butt is becoming more popular with cosmetic surgery patients

It turns out that Kim Kardashian's booty used to be something that others strived to achieve. Many plastic surgery patients went to their doctors to request a replica of the "Keeping Up With The Kardashians" star's backside but that is starting to change as Kim ages.

Instead, Dr. Rollins confirmed that Kim's little sister Kylie Jenner actually owns the preferred derriere now and that patients have been coming in to request a backside that resembles the more youthful, youngest sister.

Things have gotten so bad with Kim Kardashian's backside that Dr.

Rollins even said that at this point, there's not much she can do to fix it. Instead, she'll just have to keep airbrushing photos to make it seem perkier than it really is. That won't go down well with "KUWTK" fans, who have long envied Kim Kardashian's butt. After the unretouched Kim K. bikini photos were leaked, the "Keeping Up With The Kardashians" star lost more than 100,000 followers on Instagram. Considering that she still has several million who hung on, she'll probably survive the recent saggy butt scandal and be just fine.
