Grammy Award-winning rapper and entrepreneur Kanye West has been accused of bullying Yeezy–formerly owned by Adidas–staff with “hardcore” pornography.

According to Rolling Stone, Kanye has been accused of showing the pornographic imagery to Yeezy employees in order to assert dominance over them. The imagery allegedly included an intimate photo and raunchy video of his then-wife, reality TV personality and entrepreneur, Kim Kardashian. He allegedly showed the picture a prospective collaborator and pornography clip to several employees while on the clock.

In response to Ye’s alleged behavior, a former high-ranking Yeezy staffer sent a letter to Adidas’ executive board titled “The Truth About Yeezy: A Call to Action for Adidas Leadership.” In it, the board was encouraged to take accountability for the entertainer and designer’s actions.

According to the letter, several employees alleged that Kanye created a work culture that included “years of verbal abuse, vulgar tirades, and bullying attacks” and a “very sick pattern of predacious behavior toward women.” They even claimed that he showed one of the explicit videos of Kim during job interviews on multiple occasions.

One Yeezy collaborator additionally accused the Chicago native of showing his sex tape collection to employees while they were working on new designs. The collection included a graphic video featuring a “strap-on dildo.”

“He showed me the video of Francesca Le, a buff porn star with a strap-on dildo fu**ing another girl in the a*s. He’s like, ‘What do you think of it?’ Not laughing at all,” a former collaborator shared with Rolling Stone.

Yeezy workers not only called Kanye out for his alleged intimidation tactics, but they also called Adidas out for not taking enough action.

“The most troubling behavior that should have been flagged by the executive team very early in the partnership is his manipulative and fear-based approach to leading the team, all while trying to assert dominance over Adidas employees in closed rooms,” the letter said.

Earlier in November, paparazzi caught up with the DONDA rapper, who told them that he believed his mother, Donna C. West, was “sacrificed.” She tragically passed away in 2007.
