Klum and her former co-host Gunn, 71, both exited “Project Runway” seven years ago, with the Sports Illustrated Swimsuit cover star sharing a heartfelt goodbye at the time.

The supermodel and executive producer Michael Rucker discuss their homecomings to the series, the dynamic cast and why Christian Siriano remained as the designer’s mentor with the network shift.

Since its debut in 2004, "Project Runway" has bopped across networks, beginning first with Bravo from 2004 to 2008 and again from 2019 to 2023. The show spent nearly a decade on Lifetime from 2009 to 2017. Now for Season 21, the series has found a new home: Freeform.
