The Truth About Lauren Conrad And Heidi Montag's Feud

When the show first aired in 2006, it was set as a sequel to Lauren Conrad's high school experience showcased on MTV's "Laguna Beach." She moved to the big city of Los Angeles to live with her BFF, Heidi Montag, (via The Things). 

The reality show featured Conrad and Montag attending college at the famous fashion school, Fashion Institute of Design & Merchandising, and doing typical L.A. things. Conrad had an internship with Teen Vogue, Montag worked in events, and the pair partied often with their group of friends. It was the typical 20-something experience.

Things went south quickly, however. When Montag started dating the show's most notorious villain, Spencer Pratt, the relationship between Montag and Conrad began to fade. Conrad hated Pratt, and the feeling was mutual. The feud came to a head when Montag ditched the apartment she shared with Conrad to move in with Pratt.

This seems like a normal friendship breakup. However, things got worse when Pratt and Montag did the unthinkable.
