Supermodel Beverly Johnson has made some pretty serious allegations against Billy Cosby.

The 62-year-old wrote a piece for Vanity Fair, accusing Cosby of drugging her in the mid-80s. Johnson wrote that this all happened after she was invited to play a role on the popular Cosby Show. After taking a tour of the set, Johnson writes that Cosby invited her and her daughter over to his home one weekend to go over lines. Johnson explains that the experience was “a perfectly laid out plan,” because when the model returned the a few days later, Cosby had drugged her.

After joining him at his house for the second time, Johnson explains that Cosby insisted she drink the espresso he gave her, even though she told him she didn’t want it. It was during her second sip that Johnson reportedly realized she was drugged. “Now let me explain this: I was a top model during the 70s, a period when drugs flowed at parties and photo shoots like bottled water at a health spa. I’d had my fun and experimented with my fair share of mood enhancers. I knew by the second sip of the drink Cosby had given me that I’d been drugged—and drugged good,” Johnson wrote.

She then goes on to explain the horrific incident that involved Cosby manhandling her by angrily grabbing her wrist and waist. “I recall his seething anger at my tirade and then him grabbing me by my left arm hard and yanking all 110 pounds of me down a bunch of stairs as my high heels clicked and clacked on every step. I feared my neck was going to break with the force he was using to pull me down those stairs.”

The end result was Cosby allegedly throwing Johnson in cab and sending her home. She states she waited this long to tell her story because “black men have enough enemies out there already, they certainly don’t need someone like you, an African American with a familiar face and a famous name, fanning the flames.”

Cosby’s reps have yet to respond to Vanity Fair. Johnson is one of many women who have come forward this year accusing Bill Cosby of this and similar behavior. Read the full story here.
