Gisele Bundchen was brought to tears when an unnamed fashion boss forced her to walk topless in her first catwalk show.
The supermodel recalled how she sobbed with "embarrassment" upon realizing her breasts would be exposed for all to see during an Alexander McQueen presentation back in 1998, when she was just 18.
Opening up about the drama in her new book, Lessons: My Path to a Meaningful Life, Gisele wrote: "This was my first big international show, and I had no idea how it worked. It was definitely fewer clothes than I'd ever worn on any runway.
"I began to cry. I had no idea what to do. Mostly, I thought about how disappointed and embarrassed my parents would be. I tried to hold back my tears, but they just kept coming down, and the black feathers glued to my lashes began coming unstuck."
The Brazilian star, now 38, was saved by make-up artist Val Garland, who painted her chest with white make-up so it looked as if Gisele was wearing a thin top.
"If Val hadn't shown up just then, I seriously doubt I could have walked the runway," she explained. "I remember thinking that if anyone took photos of me, at least my parents wouldn't be able to recognize me in my black wig."
Gisele has opened up about many of her insecurities and issues in her memoir, including a segment in which she shares details of the suicidal thoughts she experienced as she battled anxiety.
"I had a wonderful position in my career, I was very close to my family, and I always considered myself a positive person, so I was really beating myself up," she told People magazine. "I felt like I wasn't allowed to feel bad, I felt powerless."
