Plastic surgery doesn’t always turn out the way people want it to – and that’s true for celebrities as well as the rest of us.

Just take a look at these 14 A-listers – and what plastic surgeon Dr. Anthony Youn, who writes the popular Celeb Cosmetic Surgery blog, has to say about each.

Celebrity plastic surgery disasters

Kenny Rogers

“Kenny Rogers gambled with plastic surgery – and lost!” says Dr. Youn.

“I’m not happy about it,” the country crooner told People magazine in 2006 of a botched eyelid lift. “It drives me crazy.”

With his tight eyelids, he no longer looks like the scruffy, masculine man we knew in the 70’s, says Dr. Youn.

Joan Rivers

Joan Rivers admits to having had lots of plastic surgery, including a facelift, neck lift, and eyelid surgery – and she makes no apologies. Some might say her “work” has been overdone, but who cares?

“She’s A Piece of Work (in a good way),” Dr. Youn says.

Donatella Versace

The first thing one notices about Donatella Versace is her overly plump upper lip. Natural lower lips tend to be about 50 percent larger than the upper lip. But in Versace’s case, the proportions are reversed, yielding what Dr. Youn calls a “trout pout.”

In addition, the designer’s skin looks waxy, possibly the result of multiple laser treatments.

Michael Jackson

A whittled-down nose, lightened skin, an unnatural cleft in the chin, a chin implant, lip augmentation, and God knows what else – Michael Jackson was a classic case of body dysmorphic disorder (BDD), Dr. Youn says.

BDD is a psychiatric condition that makes it impossible to see oneself as others do. This unrealistic view causes BDD sufferers to undergo multiple plastic surgeries in a misguided attempt to correct a defect – one that wasn’t there to begin with, according to Dr. Youn.

Jocelyn Wildenstein

“Jocelyn Wildenstein is a poster child for plastic surgery gone wrong,” says Dr. Young.

The “Lion Woman of New York” reportedly underwent dozens of plastic surgeries – all in a misguided attempt to win back her husband.

Dr. Youn thinks she might have undergone a brow lift, facelift, lip plumping injections, chin augmentation, fat grafting and/or cheek implants, upper and lower eyelid surgery, and canthopexy, a procedure that elevates the eyes to give them a catlike appearance.

Heidi Montag

What more can be said about Heidi Montag?

“She underwent 10 cosmetic surgeries in one day… and now she looks less like a person and more like a Barbie doll,” says Dr. Youn.

“In my opinion, none of these ten plastic surgeries have benefited her except in giving her more publicity and more reasons to do more surgery,” says Youn.

The reality star admitted to having a mini brow lift, botox in her forehead, a nose job revision, fat injections in her cheeks, a chin reduction, neck liposuction, ears pinned back, second breast augmentation, liposuction on waist, hips and inner thighs, and a buttock augmentation.

“This troubled fame addict needs a shrink, not a plastic surgeon!” says Youn.

Montag herself has since called the surgeries a mistake.

“People have fewer scars from car accidents than I have on my body,” she told Life & Style Weekly.

Jennifer Grey

“Jennifer Grey is a good example of how a nose job (rhinoplasty) can dramatically alter one’s appearance,” says Dr. Youn. “The removal of the bump (dorsal hump) on Grey’s nose made her look very different from the ‘Baby’ character she played in ‘Dirty Dancing.'”

That nose was one of Grey’s defining features (like Julia Roberts’s lips, Cindy Crawford’s mole, and David Letterman’s gapped teeth).

While her altered appearance didn’t stop Grey from winning “Dancing with The Stars,” it might have gotten in the way of movie roles.

“I personally think she looks better since it’s just a tad smaller,” says Dr. Youn. “But the problem is that she doesn’t look like she used to.”

Mickey Rourke

Mickey Rourke appears to have undergone a facelift and upper eyelid lift, as well as hair transplants, according to Dr. Youn.

A badly done facelift can cost a man his sideburns, and Dr. Youn says this seems to have happened with Rourke.

“The unnatural curve between his ear and cheek and his now-attached earlobe are also telltale signs of a facelift,” he says.

Carrot Top

These days, “Carrot Top is looking more and more like a muscle-bound cartoon character,” says Dr. Youn.

He seems to have undergone quite a few changes over the years, Dr. Youn says, yielding an excessively arched brow and a smooth face, possibly the result of laser treatments or chemical peels.

“At least it appears he’s left his eyelids alone,” Youn says, “although maybe they’re next.”

Priscilla Presley

What if Elvis could see Priscilla now? Dr. Youn says he might be “All Shook Up.”

A few years ago, says Dr. Youn, Priscilla Presley revealed that she got silicone injections in her cheeks – by a phony doctor. That may explain her puffy face – but not her face’s waxy look. Dr. Youn says the latter might have been caused by a combination of repeated laser treatments and Botox.
