Burn! Find Out Which Fashion Mogul Is 'Not Impressed' With Kendall Jenner's Modeling Skills

The 20-year-old mega model might have landed a major Calvin Klein ad campaign, but there's at least one person that isn't too happy with the final result — former designer Calvin Klein himself!  

During a recent interview at the at Savannah College of Art and Design, the style mogul didn't sugarcoat his thoughts on the KUWTK's performance for his former fashion brand, calling it "disappointing."  

No longer holding the reigns of the brand he once founded, he revealed he's "really not that familiar with" Kendall's involvement.  

And though he's "sure she’s a lovely young woman," he confessed "it's not "the kind of thing" he would have signed off on. However, there's one celebrity that's a-okay in his book: Justin Bieber!  

“So many people wanted to be on a billboard or in an ad or in a commercial, and for sure Justin Bieber wanted to do it. I thought that was really good," he stated. Do you agree with Calvin's opinion? Blast off in the comments below!
