Demi Moore victim of 'worst Photoshop ever'

W magazine is facing the wrath of entertainment bloggers after a chunk of Demi Moore's hip was apparently Photoshopped out of the cover of its December issue.

PHOTOS: Worst Photoshop disasters

In the image the 47-year-old actress's hip appears to have been cut several centimetres skinnier than it should be above the cut of her sarong.

Some bloggers are calling it the "worst Photoshop ever", and even the Chaser's Chas Liccardello has weighed in with a comment on his Twitter yesterday.

"Either Demi Moore's been photoshopped or she needs hip replacement surgery," he wrote.

A spokesperson for W said the magazine "did not do anything unusual or out of the ordinary" to the photo, Jezebel.com reports.

"Demi is an extraordinary beautiful woman and we feel our cover reflects that," the spokesperson was quoted as saying.

But Los Angeles-based fashion photographer Anthony Citrano was quoted on several blogs as saying "it's simply bad art".

"When I look at it I can't appreciate it because I feel like there's a piece of dirt stuck in my eyeball," he said.

"A neon arrow pointing at the f*** up. When I see images like this I feel bad for the photographer, feel bad for the subject, feel like someone, somewhere, is a dumb-ass."

The controversy follows other highly-publicised recent instances of photoshopping, including two images by Ralph Lauren that caused their models to look impossibly skinny.
