So that rumor about how Lauren supposedly hooked up with JustinBobby behind Audrina's back finally made it onto the show. Lauren denies it and is now mad at Audrina for even asking her about it, as is JustinBobby, who said that the whole thing was "immature, dude" and got up and walked away after avoiding Audrina's calls and texts for days. For people who say they didn't do anything wrong, their reactions are pretty strong. Apparently, the whole thing started when someone named Dino — who is never seen on the show, but mentioned several times — told Audrina "in detail" about the alleged hookup. (Dino is totally to The Hills what Tino was to My So-Called LIfe.") Tearful confrontation clip above.
