"Project Runway" filmed at New York Fashion Week on Thursday.  Jessica Simpson took her seat as guest judge in a super-short, sparkly silver minidress, but she had nothing on the models, who wore an extraordinary number of hot pants.

Ten aspiring designers showed their collections to Simpson, Heidi Klum, Michael Kors and Nina Garcia, although several knew they already didn't make the cut and won't be the Season 8 winner. But extra designers needed to participate to keep secret the winners and losers of episodes that haven't yet aired.

"Project Runway" was one of the big events on the day's roster at Lincoln Center, the new home for the seasonal fashion previews. Christian  Siriano, an alum of the show, was to show his spring styles later in the day.
