The episode that showed Heidi Montag and Spencer Pratt's wedding was difficult to shoot. Lauren Conrad and Kristin Cavallari decided the night before to go to the wedding and the producers wanted everyone to be shocked. They stuck Lauren in one room and Kristin in the other, but the generator in the church went out. The girls waited in the church basement for hours and once the generator came back up, Kristin and Lauren came in first and second respectively. The actual reactions of the cast were in fact real.
