Adrianne Curry and Christopher Knight of 'My Fair Brady' announce separation

Christopher Knight of "The Brady Bunch" and Adrianne Curry, who appeared on VH1's "My Fair Brady" together announced their separation on Sunday, after exactly five years of marriage.

"After starting a relationship with what seemed to be irreconcilable differences, the couple has reached a period where those differences are no longer appreciated," their manager Phil Viardo said in a statement to entertainment site Hollyscoop.

"The decision was mutually reached after it became clear to both that some perspective was needed in order to assess their unique union," Viardo continued. "They still love one another but need some distance to consider their future."

Knight, who played Peter Brady on The "Brady Bunch" and Adrianne 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.

In 2005, they also starred in their own reality show, "My Fair Brady" and got married the following year after Knight proposed to Adrianne Curry on the season finale.

On Sunday, Adrianne Curry Tweeted, "May 29th, 2006 I married Christopher Anton Knight. Enjoy your weekend! I certainly am!!!"

Earlier in the month, Curry hinted at trouble at home on Howard Stern's radio show, Us Weekly reports. The reality star said at the time that she was "unsatisfied" at home and sought attention from her Twitter fans. She also admit that she often preferred masturbation to sexual relations with her husband.

Curry told OnTheRedCarpet.com at April's Reality Rocks event that the couple turned down a fourth season of the show to "concentrate on their marriage" and because VH1 wanted the reality star to have a child.

"Season three was all about my husband, my family and very much the network wanting me to conceive a child and I was not ready for a baby at the time, nor did I want to bring a child into the Hollywood environment, so we pulled the plug on the show," Curry told OnTheRedCarpet.com co-host Chris Balish at the Reality Rocks Expo in April. "We wanted to be focused on our marriage without people watching."

"Normally, they walk away [from a reality show] because they get a divorce, like Nick Lachey and Jessica Simpson," Adrianne Curry continued. "But we got to walk away on our terms, which is a lot more satisfying than having people stop watching your show and having it pulled because there are low ratings." (S)
