The Brit became the world's most in-demand model after she stripped off for her iconic Calvin Klein campaign with rapper Wahlberg in the 1990s, but she admits the job traumatised her.
She tells Vanity Fair magazine, ""I had a nervous breakdown when I was 17 or 18 - when I had to go and work with Marky Mark. It (the job) didn't feel like me at all. 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. I went to the doctor and he said, 'I'll give you some Valium.'
""It was just anxiety. Nobody takes care of you mentally. There's a massive pressure to do what you have to do (and) I was really little ... I didn't like it. But it was work, and I had to do it.""
The blonde beauty found solace in actor Johnny Depp when they began dating in 1994, but she was left heartbroken when they split after four years.
She recalls, ""Johnny took care of me. If I said, 'What do I do?' he'd tell me. (After the break-up) I really lost that gauge of somebody I could trust. Years and years of crying. Oh, the tears!""
