What better way to promote fashion than to take off a supermodel's clothes?

Heidi Klum, at the ripe old age of 38, is appearing nude in advertisements for the fashionable reality series ‘Project Runway."

The ninth season of the popular program premieres July 28 on Lifetime.

In the new ad, ‘Project Runway' host and former Victoria's Secret model Heidi Klum ditches her clothes and only sports a pink tie while using an arm to cover her chest.

"This is definitely sexier than past campaigns we've done," the mother of two tells People magazine.

Along with Klum, co-judges Nina Garcia and Michael Kors and mentor Tim Gunn are all returning to offer their honest critiques of the work produced by the 20 chosen designers vying for the show's top prize.

Kim Kardashian, Christina Ricci, Zoe Saldana and Malin Akerman are all reportedly among the celebrity judges that will be featured this season.
