Calvin Klein has revealed he had professional troubles working with Kate Moss, calling her a “difficult” person to work with.

The genius designer confessed the British supermodel was not exactly his favourite person when he cast her and Mark Wahlberg in a series of advertisements in the Eighties, reports the Telegraph.

The 67-year-old said while Moss was “a great model,” she was also a “difficult” person to team up with.

Klein said: “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.”
