Kim buys a new house after her split with Reggie Bush. Kris thinks Kim is acting too protective of her house, so she decides to throw a house party to break Kim's house in much to Kim's chagrin. Meanwhile, Khloé and Kourtney disagree on whether Scott is welcome in Khloé and Lamar's house after his awful stunts from last season.

Khloé loses her 7-carat engagement ring and worries that Lamar will freak out, but Rob finds it. Meanwhile, Bruce and Kris fight about the new garage: Bruce feels Kris is taking over "his" only space in the house; she thinks he does not appreciate all the work she has put into their home. The friction makes Kendall and Kylie worry that their parents will divorce, but the parents manage to resolve their petty issues and end up sleeping in the garage together.
