When: 2002

Cameras were rolling as Jessica Simpson and Nick Lachey exchanged wedding vows in October 2002. MTV developed a reality TV show that followed the couple as they settled into married life. Newlyweds: Nick and Jessica first aired in August 2003 and continued for a 41-episode run. The honeymoon ended relatively quickly as Jessica filed for divorce in December 2005, citing irreconcilable differences. Though their official statement said the decision to split was mutual, others claim Simpson blindsided Lachey. Whatever the case, both have moved on to other significant relationships. Lachey is currently married to Vanessa Minnillo, while Simpson recently gave birth to her first child with fiancé Eric Johnson.
