Twilight star Kristen Stewart was spotted taking her pet Chihuahua to the Westlake Village Animal Hospital yesterday....without makeup! How dare a celeb walk out in public without her red-carpet attire? I'm kidding, but seriously. She looks like hell. Either she's stoned or has been doing some serious crying. Either way, with her looking like that, I don't see Robert Pattinson wanting to take a bite anytime soon!
