What’s an easy way to upset Heidi Klum? Deprive her of the chance to say “auf wiedersehen.” During an appearance on Tuesday’s episode of “Late Night,” the Kluminator confirmed rumors that two contestants from the upcoming tenth season of “Project Runway” left the show early without warning. “There were some cowards this season,” Klum said when asked about the walk-offs. Elaborating that she believed the two contestants departed due to the pressure of the competition, she joked, “they couldn’t make it work.” But more importantly, their exits didn’t allow the “Runway” host an opportunity to offer her signature goodbye. “That really bugs me!” she said.” Season 10 of “Project Runway” premieres on Thursday, July 19 at 9/8c on Lifetime.
