Beverly Johnson, the iconic supermodel marking the 50th anniversary of her groundbreaking Vogue cover, revealed a darker side of the fashion world. She opened up to Page Six about succumbing to drug addiction while striving for the industry's ideal of being "chiseled to the bone" during photo shoots.

Back then, the belief that cocaine wasn't addictive prevailed, and Johnson, like many models, used it to suppress appetite. Encouraged by fashion insiders to maintain an extremely slim figure, she recalled surviving on a meager diet of two eggs, a bowl of brown rice, and cocaine.

“We were led to believe that cocaine was not addictive. We didn’t know cocaine was addictive. Everyone used drugs back in the day but that particular drug for models was used because we did not eat,” Johnson said, “I remember eating two eggs and a bowl of brown rice a week. I would be shaking in a cab, and I would say pull over because I have to get a bag of M&Ms.”

Johnson's breakthrough moment came in 1974 when she made history as the first Black woman to grace the cover of Vogue magazine. This groundbreaking achievement catapulted her career and shattered racial barriers in the fashion industry.

The 71-year-old, who says she's been sober for 50 years, is performing on her one-woman show, "Beverly Johnson In Vogue," at the 59E59 Theatre until Feb. 4.
