The Hills / Laguna Beach

The Hills and its predecessor Laguna Beach defined an entire generation of reality television on MTV. From Lauren Conrad and Kristin Cavallari's Laguna Beach rivalry to Spencer and Heidi's villainous reign on The Hills, these shows blurred the line between reality and scripted drama in ways that changed TV forever. The franchise returned with The Hills: New Beginnings, bringing the original cast back into the spotlight.
