Cindy Crawford confesses that she nearly quit modelling after witnessing a drug-fuelled orgy at 18.

“I was at dinner in Milan with several big photographers and several of the big models at the time, and there were people snorting coke right there,” she told ‘Maxim’ magazine.

“This one girl got up on the table, wearing a short skirt and nothing underneath. I called my mom, and said, ‘I can’t do this. Get me re-enrolled’ — that first experience was so in-my-face.”
