Eva Longoria Parker and Christina Aguilera to Guest Judge on "Project Runway"

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.

The highly anticipated return of Project Runway will pit 16 up-and-coming designers against each other in a bid to win $100,000, a fashion spread in Marie Claire magazine and an all expenses paid trip to Paris for two. Klume says we should watch out for the ladies this season, "The girls are very strong on season six—there's a lot of crying, there's fighting going on, there's a lot of drama going on, but especially with the girls."

The season premiere featuring Lindsay Lohan airs Thursday, August 20th at 10PM on the Lifetime Channel.
