'She looks like an alien': Kardashian fans slam Calvin Klein for photoshop fail as they say Kim looks like a 'totally different person' in new campaign

Kardashian fans have taken to Twitter to criticize Calvin Klein for its new campaign images which they claim are heavily photoshopped.

Many accused the clothing label of editing Kim Kardashian to the point where she's no longer recognizable with some even comparing her to an alien as she poses next to her siblings.

The 37-year-old's image prompted some fans to ask where the real Kim was on the day of the shoot.

'I’m certainly not a hater because I loooove the Kardashians. But the photoshop on this picture is ridiculous. And I don’t mean kylie. why does Kim look like an actual alien? That’s not how she really looks!' wrote user Amy Candler.

'They photoshop Kim into a different person' another fan chimed in.

'I don't know what the f*** Calvin Klein thought they were doing but that is not kim kardashian in that campaign' tweeted @sickboygreg.

Another user's scathing critique accused Calvin Klein of making Kim look like a 'high quality sex doll'.

And it wasn't just Kim's face that was the focus of attention, her left arm was a point of debate as observers at first though there was a large chunk missing before realizing it was a shadow.

The image in question shows Kim sprawled out on a patterned blanket beside her sisters Kourtney, Khloe, Kendall and Kylie but for some reason only Kim has the dark shadow, cast from her bra, on her arm.

Kylie, 20, who still hasn't confirmed her pregnancy, wasn't safe from the scrutiny with many fans having a giggle at how she's hanging onto the blanket which covers her tummy for dear life in several of the images.

'they can photoshop @KimKardashian enough to make us question whether it's really her, but they can't photoshop @KylieJenner bump out, she has to wear a duvet A DUVET #obsessed'

'What is under Kim's arm?' Fans think the fashion line failed with their photo editing

However the weirdest theory is that Kylie wasn't part of the photoshoot at all and a body-double was used and her face photo-shopped in afterwards as Twitter users pointed out the differences in lighting on her face.

The spring/summer campaign represents the latest iteration of the evolution in the CALVIN KLEIN brand’s globally recognized #MYCALVINS call to action: Our Family.

Shot by photographer Willy Vanderperre, the latest chapter of this new campaign features the siblings are featured wearing styles of underwear which are already out in stores.
