Many of the show's romantic storylines were either entirely or mostly fabricated. Amongst other items: Brody Jenner never dated Lauren Conrad and only had a brief fling with Kristin Cavallari that happened years before either of them were on the show; Kristin's romantic storyline with Justin Brescia was completely fabricated, as she was not attracted to him at all and only agreed to film fake romantic scenes on the condition that they were very short and never implied the two were having sexual relations; and Audrina Patridge's relationships with Brescia and later with singer Ryan Cabrera were very short affairs that were "resurrected" around a brief real-life breakup between Audrina and her longtime boyfriend (now fiancée and father of their future child) Corey Bohan.
Spencer Pratt and Heidi Montag were fired from the series after threatening a producer. They would later claim in interviews that the show conspired to make them falsely look evil and to make Lauren Conrad falsely look good, but in the process Spencer also finally admitted that Lauren's view that he spread false rumors about her having a sex tape were true, and that he did so to get revenge on her for trying to get Heidi to break up with him.
