Kristin Cavallari appears on "Watch What Happens Live" (Bravotv.com)

In a game called "Plead The Fifth" where guests are asked three difficult questions and they can only skip one, host Andy Cohen asked Kristin how fake the show was. "Oh I don't mind answering this question," Kristin said. "Pretty fake [with] fake relationships and fake fights. I'm sorry." 

She admitted her on-screen romance with Justin wasn't real. "I never really dated him," Kristin said. "I think I made out with him once and that took a lot of convincing." 

Finally, when the topic turned to nemesis Lauren Conrad, Kristin admitted their relationship isn't that bad. I feel [producers] put things in our head," Kristin said. "We were 17 and 18 and they made it a lot worse than it was."
