Supermodel Miranda Kerr has been photographed topless by husband Orlando Bloom for the new Rag & Bone fashion campaign.

The ad-hoc pictures, which show Kerr horsing around on a wharf and in various states of undress, form part of the denim label's 'DIY Project', in which a chosen group of models have been given "free reign" to make their own ad campaign.

"No stylist, no hair and make-up, no lighting," says the ad tagline. "Just a girl and her camera, and Rag & Bone."

Abbey Lee Kershaw, Karolina Kurkova, Carolyn Murphy and Lily Aldridge are just a few of the other models that appear in the 'DIY Project', with the latter snapping Kerr while she was in New York.

Miranda Kerr To Wear Bombshell Bra At Victoria's Secret Show

"Rather than do what every other brand does and have a high-end photographer take very polished shots, we thought, "'Let's flip it on its head to get the girls to take over,'" explained Rag & Bone designer Marcus Wainwright. "We wanted it to be very real."

And real it was, with Bloom capturing Kerr, on the shores of New Zealand while on a break from filming The Hobbit.

The supermodel, who's set to don the coveted $2.5 million Bombshell bra in the upcoming Victoria's Secret show on November 9, commented recently that she was glad to be modelling again.

"It's very special," said Kerr. "And now I feel better than ever. I feel healthier than I've ever felt. It was wonderful to have a bit of time off after I was pregnant and having Flynn. But now I'm back in the swing of things and it feels good."
