After a wild (and rumor-filled) weekend in Miami, Kristin swings by Audrinas place to invite her to a barbecue -- and find out what she thinks about rumors of Kristin's out-of-control partying. Audrina says she plans to bring her new boyfriend, singer Ryan Cabrera, but when she asks if Stephanie and Lo are on the guest list, Kristin admits she suspects them of spreading lies about her in Miami. Audrina admits she doesn't know who started the rumors, but says Lo and Stephanie might've gotten confused when Kristin stood them up to go partying with Stacie. Unconvinced, Kristin hints that the girls didn't waste any time jumping to conclusions and points out that "anytime there's a problem, Stephanie's involved." Kristin resolves to "get to the bottom of this and end this."
