Look out for the claws on these resident mean girls of reality TV
Kenley Collins and Heidi Klum, Project Runway
The pin-up designing finalist could not take constructive criticism. She consistently talked back to the judges -- giving Klum some eye-rolls and more than a few "whatever" remarks and told Michael Kors that she doesn't "follow collections." And if that wasn't catty enough, Collins was arrested in March for assaulting her fiance, Zac Penley, with their pet cat!
