Remember the old children's song, "Head, Shoulders, Knees and Toes?" Kendall Jenner and Gigi Hadid may have a hard time demonstrating the dance. The models posed for the 10th Anniversary Art Issue of W Magazine. The cover shoot shows Jenner holding and adorable white and brown puppy while Hadid offers her a drink. The bizarre image also shows a chicken in a tent photobombing in the background and a drone by their feet. Oddly enough, the props are normal considering they actually exist in the real world.

What has heads tilting sideways isthe removal of their knee caps. Both models have at least one knee removed. The smooth appearance is reminiscent of the way a Barbie doll's legs look.

Were thephotoshoppedknees intentional or an epic fail?

The error was spotted by many on social media including users on Twiiter. Many Twitter users used their 140 characters to express their disappointment with the shoot, saying it's another photo depicting unrealistic body images.

The two models haven't responded to the outcry, but according to Buzzfeed, a rep for W Magazine was contacted for a comment and said: “The images of Kendall and Gigi are part of a project by artists Lizzie Fitch and Ryan Trecartin, who are known for their deliberate use of digital technology, combining distortions with makeup and prosthetics.”

Artists Lizzie Fitch and Ryan Trecartin conceptualized the spread.

The two models also shot a performance art video were they recreated four iconic art pieces including those fromYves Klein and Yoko Ono. Jenner and Hadid are described by Trecartin as "super friendly, domesticated humanoid pets."

How did Jenner and Hadid become Placebo Pets?

According to an article from W Magazine, the BFFs shot the controversial photos in August in Culver City, California. Aside from their somewhat natural-looking human photos (ignore the knees) the models were also transformed intoPlacebo Pets.

Hadid was a lion-fox with pointy ears and Jenner a bunny-cat, all with the help of prosthetics and a green screen.
