The old Project Runway adage proves true: one minute you’re in, the next you’re out — only this time, it’s the judges being aufed. Jennifer Lopez has long been booked as the guest judge for this season’s runway finale (an honor that Victoria Beckham held last season), but at this morning’s taping at New York’s Bryant Park, host Heidi Klum announced that J. Lo has canceled at the last minute due to a foot injury. Faced with filling the spot in a day’s time, the show has turned to co-host Tim Gunn to fill the vacated judge’s chair. Amazingly, it’ll be the first time in five seasons that the workroom mentor has a place on the judging panel. “It was a thrill and an honor,” Gunn said of his appointment, adding that he promises to be unbiased.
