"Bravo, along with show producers the Weinstein Company and Miramax, announced Thursday that Tim Gunn would be back to knock another season's worth of straight-talking design sense into the often feuding aspiring couturiers.
"I am thrilled to make it official that I will be back in the workroom for season four of Project Runway," Gunn said. "We are in the midst of casting the designers now, and I can already see that it will be another amazing season."
