Dickinson, who began her modeling career in the 1970s and claims to have coined the word "supermodel," bashed the idea of Kim Kardashian and Kendall Jenner being models during an interview on AfterBuzz TV's The Tomorrow Show With Keven Undergaro.
"They're not models," Dickinson insisted on Monday when the topic of Kardashian and Jenner frequently landing magazine covers was broached.
When asked specifically about 21-year-old Jenner -- who has walked runways and posed in campaigns for major designers, like Calvin Klein; graced the cover of Vogue; and starred in The Victoria's Secret Fashion Show two years in a row -- Dickinson said, "I think she's lovely."
However, Dickinson, 61, continued, "Don't get me wrong, but I don't think she's a supermodel, I don't."
Dickinson explained that Jenner and her bestie Gigi Hadid are only in demand with designers and photographers because of their huge followings on social media, especially Instagram.
"Give me a break. You think that's supermodel?" Dickinson told The Tomorrow Show when looking at a photo of Jenner. "That is not supermodel... She can't beat me. She can't. Apples and oranges."
Dickinson also admitted she was "shocked and disappointed" to see that Vogue editor-in-chief Anna Wintour allowed Kardashian and her husband Kanye West to grace its cover in 2014 after their wedding.
"Kim Kardashian made the cover of Vogue, which made me want to vomit. It was crazy," Dickinson vented.
The former modeling agency owner continued, "They're not models! They're reality TV stars! You know, modeling is extremely hard work, you have to have perfect proportions."
Getting one last slam in, the newly-married model noted, "The Kardashians do not have couture proportion."
