Heidi Klum returned with a new poster for the 13th season of "Project Runway". Heidi poses nude for the artwork of the upcoming season of the Emmy-winning TV show which will premiere on July 24.

In the picture, Heidi actually wears nothing but a pair of nude strap heels. Her toned body is covered by a digitally imposed hanger dress. The judge of "America's Got Talent" is photographed together with Tim Gunn, who wears a checkered suit while glancing at the camera.

Heidi told Us Weekly about the photo session, "It was a little bit embarrassing because I had to shoot it basically without clothes on. I kept on apologizing to Tim having to stare at my booty, and he was like, 'Oh! Good god! I love looking at your booty!' It's funny because he's so polite and I had to run in front of him and he was making faces behind [me]. I was wearing the tiniest little G-string."

"Project Runway" received its 10th Emmy nomination for Outstanding Reality-Competition Program on Thursday, July 10. Heidi revealed she's still nervous about the achievement although it's been a decade since the show was premiered. "I've been thinking about it for days," she claimed, "I've been sweating bullets about it! I totally do, because you never know."

Heidi dished on the upcoming season of the Lifetime reality series, "We have great people on-Dita Von Teese was there for an amazing judging session. We did a rain walk so we had the models walk through rain. We built an amazing set where the designers had to create an avant-garde look out of waterproof materials... the most amazing things happened."

She added, "My dream [judge] would be Michelle Obama. I hope she would come one day!"

Last year, the promotion picture of "Project Runaway" was allegedly banned from Los Angeles billboard. The picture featured fully-dressed Heidi and Tim who were surrounded by nude models.
