'Brady Bunch' Star Christopher Knight Separates from Wife Adrianne Curry

'Brady Bunch' star Christopher Knight and his model wife Adrianne Curry have separated after five years of marriage. 

The split was announced by the couple's manager, Phil Viardo, who acknowledged the pair's prior marital troubles. "After starting a relationship with what seemed to be irreconcilable differences, the couple has reached a period where those differences are no longer appreciated. The decision was mutually reached after it became clear to both that some perspective was needed in order to assess their unique union," Viardo said in a statement to ET. 

It is the third marriage for 53-year-old Knight, who shot to fame in 1969 while starring in the popular TV series "The Brady Bunch." It is the first marriage for Curry, 28, who is best known as the first winner of the reality competition "America's Next Top Model." The couple has no children.

The pair first met while taping VH1's "The Surreal Life" and their rocky
relationship was later exposed during three seasons of another VH1 reality show,
"My Fair Brady."
