She has L.A. nearly conquered, but she has to yet find the one person to share it with, and when she crosses paths with Justin-Bobby, sparks fly. Audrina seems to have moved on from Justin, with a new man in her life, but that doesn't mean she's ready to see him with another girl, especially not Lauren's old rival Kristin. Meanwhile Brody is still with his Playmate girlfriend Jayde, but with his ex-girlfriend Kristin back on the scene, how long can that last? Heidi and Spencer are moving to suburbia and a life of wedded bliss, but they'll quickly discover that married life isn't as perfect as their storybook wedding.
