If you were hoping to add Project Runway 4 to your must-see list this summer, you’re going to have to wait a bit. Bravo announced that the latest season will not air until late 2007, despite the excellent ratings from last summer’s edition. Never fear, though… Bravo will be offering up plenty of summertime reality fare, including a third season of Top Chef, Hey Paula! and the third season of Kathy Griffin: My Life on the D List. No firm date on when Project Runway 4 will air, but Bravo’s press release stated that “only three finalists… face-off.. at New York Fashion Week.” This is a departure from the four finalists in the previous season. But the good news is that Tim Gunn will return for the fourth season, as well as fashion designer Michael Kors, ELLE Magazine fashion director Nina Garcia and Heidi Klum.
