Kate Moss is opening up about a traumatic modeling experience she had at age 15.

While appearing on a recent episode of the “Fashion Neurosis with Bella Freud” podcast, the supermodel, now 50, described being pushed to model topless as a teen, even though it made her extremely uncomfortable.

Moss said she was being photographed by British fashion photographer Corinne Day for The Face magazine, and that even though she “never wanted to be topless,” the photographer suggested that Moss would lose future job opportunities if she didn’t do as asked.

“I had to get over it because the photographer was like, ‘If you don’t do this, I’m not gonna book you for the next job,’” she said.

To make matters even worse, Moss added, her brother was bullied over the revealing images.

“Luckily, The Face wasn’t really sold in Croydon,” she said, referencing her hometown. “I don’t think anyone really saw it. But I mean, they heard… They took the piss out of my brother, like ‘Oh your sister has her tits out.’ He probably suffered more than I did about it.”

She explained that she dealt with her discomfort at the time because “you can’t be very self-conscious because your body’s kind of not your own when you’re a vessel for somebody else’s imagination.”

Moss was scouted at age 14 by Storm Management modeling agency in JFK International Airport.

The English supermodel has previously shared regrets about her famous 1992 Calvin Klein shoot with Mark Wahlberg and photographer Herb Ritts, in which she also posed topless.

In a cover interview with Vanity Fair in December 2012, she revealed that the photoshoot with Wahlberg made her have a “nervous breakdown.”

“It didn’t feel like me at all,” Moss explained. “I felt really bad about straddling this buff guy. I didn’t like it. I couldn’t get out of bed for two weeks. I thought I was going to die.”
