Calvin Klein has thrown some SERIOUS shade at Kendall Jenner

She may be the face of the brand, but that doesn't mean its founder, Calvin Klein, has to be as head over heels for Kendall Jenner as the rest of us, but still…

Calvin, who, in fairness, gave up control of the company more than a decade ago, was far from gushing when it came to the 19-year-old Calabasas-native.

According to OK! magazine, the fashion designer spoke to Fern Mallis of the Savannnah College of Art and Design, and admitted that Kendall's campaign hasn't made that big an impact on him.

"You know, I'm really not that familiar with it. I'm honestly not. I'm sure she's a lovely young woman. It's not the kind of thing I would have done, even today," he admitted.

Throwing shade at today's generation of catwalk heavy-hitters, the 73-year-old said: "Now, models are paid for how many followers they have."

"They're booked not because they represent the essence of the designer, which is what I tried to do – they're booked because of how many followers they have online," he added.

Despite the fact this this seems to be working wonders for fashion houses and the models themselves, Calvin doesn't seem convinced.

"I don't think that, long-term, is going to work. I don't think that's a great formula for success for the product you're trying to sell," he opined.

Oooh…the gloves are off.
