Christina Aguilera and actress Lindsay Lohan are to appear on Project Runway. Both stars have signed up to make a cameo appear in the new season of the series in Los Angeles. Supermodel and host of the show, Heidi Klum said of Project Runway, “We all had a lot of fun. We laughed a lot and we saw some great fashion." 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." Filming finished in February, but the show will air someday in August.
