London: Former Girls Aloud singer Cheryl Fernandez-Versini admits she is unconvinced by the authenticity of Kim Kardashian's nude shoot for Paper Magazine.
The controversial image shows Kardashian's body is covered in oil as she exposes her rear - but Cheryl, 31, is not convinced that the images haven't been tampered with, reported Contactmusic.
"I don't think it's real. I'll refrain from judgement because each to their own. But I would never do it. I could never. I could never. I could never," she said.
Despite attracting attention for posting a picture of her own tattooed backside online last year, Cheryl insists she's uncomfortable about stripping off in front of people she barely knows.
The 'X Factor' judge said, "I can't even get changed in front of my stylist who I've had for years. Just no."
