Tim Gunn said he'll be back for Project Runway's fifth season -- but beyond that, the fashion guru said he's unsure about his future on the Bravo reality series.

"I'm only looking through Season 5 at this point. Then we'll take it from there," he told the Chicago Tribune in a Thursday interview.  "I'll tell you that things are in flux and I don't know beyond Season 5.  I'm just thrilled to have a Season 5."

Despite his Project Runway status currently being up in the air beyond the fifth season, if Gunn has his way, it sounds like he'll be back.

"People ask me, 'Aren't you tired of this?' How could I possibly be tired of this?" he told the Tribune.  "It's invigorating and inspiring. I am the luckiest guy in the world."

Gunn previously stated auditions for Project Runway's fifth season would commence next month before taping begins in June.  Bravo subsequently confirmed Gunn's statement at the conclusion of the fourth-season finale broadcast -- meaning he'll have a busy summer ahead.

"I don't know if Bravo has announced that we are doing another season [of Tim Gunn's Guide to Style], but we are," he revealed to the Tribune.  "[We'll film it] around Runway, before and after [the filming of Season 5], which almost killed me last year but we're going to do it again."

Tim Gunn's Guide to Style, which follows Gunn as he helps hapless fashion dilemmas transform into stylish individuals, premiered last September.  While Gunn told the Tribune that test audiences thought the show was "superb," viewers will apparently see a few tweaks for the second season.

"They want more education in the show. They want to learn more," Gunn explained to the Tribune.  "They want to get rid of the underwear drawer and so do I. Thank God for [co-host Veronica Webb] because I could never have done that. They like the underwear lesson but they don't like the humiliating aspect of it."

After spending 23 years as chair of the Department of Fashion Designs at Parsons The New School for Design in New York City, it's no surprise Gunn is embracing Guide to Style's new approach with its subjects.

"Going forward we're going to have much more in the way of education and learning," he told the Tribune.  "I'm thrilled about that, because that's what I do."
