Cara Delevingne has posed topless for the latest issue of W magazine. Meanwhile, on the cover, she is labeled 'the anti role model' and is seen in a white bra top.

In the accompanying interview, Delevingne, who is the face of Burberry's Beauty Campaign, openly talked about her skin condition psoriasis, and how supermodel Kate Moss came to her rescue when it flared up ahead of a show.

"It only happened during Fashion Week!" she said, "Which is, of course, the worst time of the year for me to be covered in scabs. Psoriasis is an autoimmune disease, and I'm sensitive. Kate [Moss] saw me before the Louis Vuitton show at 3 a.m., when I was being painted by people to cover the scabs. She said, 'This is horrible! Why is this happening? I need to help you.' She got me a doctor that afternoon; Kate gives really good advice."

The 21-year-old British model, who has been romantically linked to One Direction's Harry Styles and English singer-songwriter Jake Bugg, revealed valuable relationship advice from Rihanna.

"I was just on holiday for three days in Greece with my sister, and I thought that would make me happy and relaxed. But when I stop everything, it's really bad. I go crazy. In Greece, it was a lot of couples, and I felt alone, which made me sad." Delevingne said, "I called Rihanna, she said 'It's easy to drown yourself in work. That's a form of escapism. So, if you're alone and you want to cry, cry.' And I did. But by then, it was time to leave and get back to my life."

Meanwhile, it was recently reported that Delevingne auditioned for a secondary role in the film version of EL James's best-selling erotic novel Fifty Shades of Grey.

The issue will hit newsstands on 15 August.
