Heidi Klum Talks "Project Runway" Season 10 on "Good Morning America"

Boosting interest in the tenth season of "Project Runway", Heidi Klum dropped by "Good Morning America" on Thursday (July 19) to talk about a major bombshell that unfolds during the show.

Keeping her hair simple and straight, the gorgeous supermodel greeted fans with a wave as she strutted into the ABC studios wearing tight leather leggings with a sequined top and white blazer.

Talking about when she knew the Lifetime hit would be a success Heidi, said, "When we were filming we didn't really know but when it was all cut together and you know, when we say the designers and you know the beautiful clothes we were like, 'you know what, we might be actually on to something."

Fans can expect a surprising twist this time around after the 39-year-old revealed during the interview that two contestants decided to secretly leave, explaining, "The pressure got to them they could not make it work and literally in the middle of the night they packed their things very quietly and just walked out."

Adding to the excitement, "Project Runway" has landed four Primetime Emmy Awards nominations including Outstanding Reality - Competition Program, Outstanding Cinematography for Reality Programming, Outstanding Directing for Nonfiction Programming and Outstanding Picture Editing for Reality Programming.

The competition series will kick off tonight with an outdoor fashion show in Times Square - which will air on Lifetime beginning at 9p.m. ET.
