The Vogue covergirl broke down and sobbed in a restroom during the shoot for fashion magazine The Face after being commanded to strip or face never working in the industry again.
In a rare interview, Moss, now 38, looks back on the traumatic event that shaped her career when she was a naive 16 year old trying to break into the modelling world.
She tells Vanity Fair magazine, ""I hated my boobs because I was flat-chested, and I had a big mole on one. But they said, 'If you don't do it, we're not going to book you again'.
""I'd lock myself in the toilet and cry, then come out and do it. I made the hairdresser - the only man - turn his back.""
It previously emerged on Wednesday (31Oct12) that Moss suffered a meltdown when she was 17 after stripping off for the iconic Calvin Klein underwear campaign in 1992 alongside Mark Wahlberg, then known as rapper Marky Mark.
