Christopher Knight and Adrianne Curry announced their separation on May 29, 2011. Their manager said in a statement, "After starting a relationship with what seemed to be irreconcilable differences, the couple has reached a period where those differences are no longer appreciated."
Knight filed for divorce the following August.
Knight, who played Peter Brady on The "Brady Bunch" and Curry, who won the first season of "America's Next Top Model" met on the fourth season of the ensemble reality star cast show "The Surreal Life" in 2005 and began dating. They later starred in their own reality show, "My Fair Brady" in 2005 and got married the following year after Knight proposed to Curry on the season finale.
