Season six of Project Runway is about to kick off and the rumor mill has been buzzing with big name celebs who will be making appearances as guest judges.

Fashionistas Eva Longoria Parker and Christina Aguilera will join supermodel Heidi Klum as guest judges, along with Lindsay Lohan and Rebecca Romijn. The judging panel for the hit reality show will otherwise stay the same, with top designer Michael Kors and Marie Claire's (formerly of Elle) fashion director Nina Garcia.
