Calvin Klein claims Kate Moss was "difficult" work with.
The US designer cast the supermodel in a series of campaigns in the 90s but revealed it was not an easy time, because she disliked her co-star Mark Wahlberg.
He said: "She is a great model, but it didn't go too well. She didn't like him at all. He was a pleasure. I have worked with so many women, great ones, and Kate was always difficult."
Although Klein is not a huge fan of the British beauty, she was recently described as a "fantastic" model by renowned photographer Nick Knight.
Knight - who has shot the 36-year-old star on many occasions - said: "I've known Kate for many years and she's a fantastic model.
"She can put a little black T-shirt on and make it look like the exact T-shirt you want to buy this season. And that's a real skill - she understands the narrative in clothing, and expresses that perfectly. That's her great skill."
