Karlie Kloss, Christian Siriano named host and mentor, respectively, of retooled 'Project Runway'

Following the September departures of longtime host Heidi Klum and mentor Tim Gunn, Bravo's "Project Runway" has tapped model Karlie Kloss and fashion designer and former series champion Christian Siriano to fill those respective positions.

In her announcement Wednesday, network executive Shari Levine also said fashion designer Brandon Maxwell and journalist and former Teen Vogue editor-in-chief Elaine Welteroth had come aboard to join Elle editor-in-chief Nina Garcia as judges.

"As someone who grew up watching 'Project Runway,' I could not be more excited to host and produce a series that provides a platform to aspiring American designers as they pursue their creative and entrepreneurial dreams," Kloss, 26, said in a statement.

" 'Project Runway' has offered such wonderful opportunities for so many and I’m excited to take on this role as a mentor," season-4 winner Siriano said in a statement. "I hope to guide and inspire the new talent on the rise." 

The fashion-designer competition returns for its 17th season next year.
