It was bound to happen eventually and, last night, it did: 'The Hills' heroine L. C. faced off with her archnemesis Heidi at a party. Heidi made friendly overtures but Lauren wouldn't talk to her unless she apologized. But Heidi maintained that she hasn't done anything wrong! (She did. Sex tape, something something). There was a lot of meaningful blinking and music that told you how to feel. Then Lauren said two profound and true things: "Having your boyfriend do your dirty work for you doesn't make you innocent" and "You're a bad person." She may not be smart, but she is a good judge of character.
