Talking to Vanity Fair, the iconic model admitted when she first started out, posing naked for shoots often brought her to tears.

She said: "I'd lock myself in the toilet and cry and then come out and do it. I never felt very comfortable about it.

"There's not a lot of boobs. I hated my boobs! Because I was flat-chested. And I had a big mole on one."

Kate also confessed that she felt forced into posing for the shots with photographers threatening that she would never work again if she declined.

She revealed: "There's a massive pressure to do what you have to do. I was really little. But it was work and I had to do it.

"But they were like "if you don't do it, then we're not going to book you again."

During her monumental rise to prominence in the fashion industry, Kate took a lot of flak for promoting 'heroin chic' due to her skinny figure.

Kate Moss admitted that although she was never anorexic, the lifestyle of being a model contributed to her slight frame.

She explained: "I was thin but that's because I was doing shows, working really hard."

"You'd get to work in the morning, there was no food. Nobody took you out for lunch when I started. Carla Bruni took me out for lunch once. She was really nice. Otherwise, you don't get fed. But I was never made anorexic."
