Laguna Beach is going back, back to the beginning - and revealing some behind-the-scenes romances that never made it to air. During the Friday, April 10, 20th anniversary special, titled The Reunion: Laguna Beach, the season 1 cast spilled all the tea on the relationships that were - and weren't - highlighted on the series. The reality show, which ran from 2004 to 2006 on MTV, followed the trials and tribulations of Laguna High School students as they navigated love, friendship and their impending graduation.
