Project Runway may never look the same. Mainstays Heidi Klum and Tim Gunn are leaving the show after 16 seasons to start a new fashion series for Amazon, reports USA Today. The format of the new series is still unclear, but viewers will apparently be able to buy clothes featured on it. Project Runway, meanwhile, is set to move from Lifetime back to its original network, Bravo, next year. Variety notes that Amazon's entertainment division is making some aggressive moves under its new leader, former NBC exec Jennifer Salke. The division recently signed other deals with Nicole Kidman and Jordan Peele, among others. (More Project Runway stories.)
