Mommy-to-be for the fourth time, German supermodel Heidi Klum will take over her new network home – Lifetime — with the August 20 debut of Season 6 of the hit fashion reality competition Project Runway. A two-hour special, Project Runway: All-Star Challenge, will precede the long-awaited premiere.

Also be on the lookout for Models of the Runway, a new show about the lovelies who lend their slim figures to the designers of Project Runway.
