Demi Lovato poses in the buff

Demi Lovato has bared her soul — and a lot more — in a new Vanity Fair photo-shoot. The 23-year-old singer was photographed nude by Patrick Ecclesine at the Greenwich hotel at the end of last month.

In a post on the Vanity Fair website, Patrick describes how a vulnerable Demi was still in mourning after the death of her great-grandfather the day before. But the grief inspired her to take the plunge and do the soul-baring shoot with three rules - no clothes, no make-up and no retouching.

Demi told Vanity Fair, “If there’s one thing I’ve learnt in the past day, it’s that life is too short.”

“I want to show the side of me that’s real, that’s liberated, that’s free. ‘What if we do a photo-shoot where it’s totally raw? Super-sexy, but no make-up, no fancy lighting, no retouching and no clothing. Let’s do it here, let’s do it now’,” Demi added.

Patrick said it was half past midnight when the singer de-robed for the shoot, which includes a nude snap of her back turned to the camera while sitting on the edge of the bathtub.
