Calvin Klein attempts to explain 'photoshop fail' in Kardashian photoshoot

The internet played their favourite sport - picking on the Kardashians - again recently, this time targeting a new photo that came out as part of a family campaign for Calvin Klein.

Kim Kardashian, AKA the ring-leader of the Kardashian-Jenner clan, uploaded the black and white pic for the brand's fall campaign to her 115m followers on Instagram. It features Kim standing with Kourtney and (a then-pregnant) Khloe Kardashian, as well as Kendall and Kylie Jenner. They're all looking glam in a forest scene wearing CK jeans and undies, but fans were quick to spot a bit of a bizarre photoshop fail.

Can you see it?

Yup, poor Kourtney appears to have been on the receiving end of a botched photoshop job, with her right arm looking freakishly thin.

Behind-the-scenes pics assured people that her arms are actually very normal-looking, but people were still seemingly delighted by the photo fail.

While the Kardashians have been accused of bad photoshopping more than once, and therefore seem to stay cool about the odd visual mishap, it seems that Calvin Klein didn't like being laughed at very much. In fact, the American brand released a statement to address the photoshop fail that seemed to be the internet's topic of the day.

They defended the pic by saying it wasn't a poor photoshopping effort in order to tweak the body-shapes of the Kardashian-Jenner clan, but rather an unfortunate lighting error.

"As you'll see from the high-res version of the image, there are no issues with Kourtney's arm," Calvin Klein wrote in a statement, alongside a larger image. "However, the light is hitting it which makes it slightly less defined. Unfortunately, when the image is posted to social media in a lower-resolution format, the shape of her arm loses its definition, creating the effect which social media users have commented on."

Of course, we all know that images get compressed into lower resolutions when posted online, so this seems a fair enough explanation. A closer look at the picture may indeed prove that it's just a trick of the light; it seems half of Kourtney's arm was hit by a lot of light that is almost the same shade as the background.

So, can we forgive them? I think so too.

In any case, the reality TV world's favourite family has bigger fish to fry. Since the whole CK photoshop fail debacle, Kim Kardashian has become a meme after posting this pic of herself posing in Kanye West's newest shoe creation:

And Kourtney seems to have had a bit of a rough time recently, as we know from the latest Keeping Up With The Kardashian's episode which showed a huge row between the siblings, which then escalated onto Twitter in a real-time tiff.

Still, it seems they were able to patch things up and that the fight was just your regular kind of family feud.

What kind of drama will the Kardashians bring us next week?
