One would have to be pretty naive to believe that celebrities naturally look flawless all the time. But we wouldn't blame anyone for being duped, especially since the high-gloss world of magazines, ads and catalogs practically demands nothing but perfection in their spreads.

And when extreme dieting and exercise isn't enough, that's when they tend to go crazy with the Photoshop tools. Below are some of the most hilarious celebrity Photoshop flubs of all time. See if you can spot what went wrong:


Oprah Winfrey's head was pasted onto the body of '60s star Ann-Margret on the August 1989 cover of TV Guide. Neither stars were asked permission, and a rep for Oprah told the AP: "Oprah would not pose on a pile of money like that."


There's no denying that Demi Moore is drop dead gorgeous, but this cover for W magazine's December 2009 issue ended up accidentally dislocating her hip bone.


Country music singer Faith Hill appeared on the July 2007 cover of Redbook. This gif from Jezebel shows that they shrunk her left arm, got rid of the wrinkles and face lines, and even cropped her back fat.


Female celebs aren't the only ones who become victims of extensive photoshopping. When tennis pro Andy Roddick appeared on the cover of Men's Fitness, even he couldn't believe his "22-inch guns" in the retouched photo.


This iconic image of OJ Simpson's mugshot really incensed a lot of folks. Captured after he was arrested for the murders of his ex-wife and her alleged lover, TIME Magazine's version was accused of making Simpson appear more sinister in an attempt to persuade the public he was guilty. Newsweek's version of the original photo shows a clear difference between both images.


Who can forget this image of a scantily-dressed Katy Perry on the cover of Rolling Stone?The photoshop transformation ended up lifting her breasts, thinning her thighs, shifting her hand, and erasing all of her skin imperfections.


This notorious pic of Kim Kardashian which was shot for the April/May 2009 issue of Complex Magazine.
The original photo (top-left) had accidentally been uploaded on the Complex website. But Kim took it all with stride by stating on her website, "So what: I have a little cellulite. What curvy girl doesn't!?"

 
During the hey-days of the “Twilight” saga, Kristen Stewart was featured on the cover of Glamour's November 2011 issue. Unfortunately, she seemed to have left her left forearm at home.


When Paris Hilton landed a Vanity Fair Spain cover, the graphic designers decided to give her a complete Barbie-like makeover which included fixing up her wonky left-eye.


The March 2013 cover of Harper's Bazaar China featured an almost unrecognizable Sarah Jessica Parker, which included sharpened cheekbones and piercing eyes.


The February 22, 2010 issue of Hello! magazine ended up transforming the future king of England into a sullen goth. But at least they added more hair to his crowning glory.


Vogue Russia featured Adam Levine and then girlfriend Anne Vyalitsyna on the cover of the November 2011 issue. While Anne looked immaculate, Adam ended up losing a part of his torso.


This September 2009 Self cover of Kelly Clarkson had readers accusing the magazine of digitally shedding the pounds off the singer. Editor-in-Chief Lucy Danziger defended the cover saying they were just trying to make her look "her personal best."
