The couple put their love and arguments on display for all to see when they signed up for the MTV show in 2003, which documented their life as husband and wife.
The show aired for four seasons and wrapped in early 2005 -- just months before the singers split.
But Simpson is refusing to blame the invasive show for contributing to her and Lachey's divorce, insisting she only has fond memories of her time on the small screen.
She tells the June issue of Vanity Fair magazine, "In all honesty, I believe it did not affect our marriage because we enjoyed watching those episodes, and that will always be a time I cherish. It made me understand what marriage is, what love is, what commitment is.”
And Simpson reveals her new beau, football star Tony Romo, was also a fan of the series: "(He's seen) a couple episodes. He thought I was cute."
MTV's reality series have become famous for documenting the lives of doomed couples -- Britney Spears and Kevin Federline split in 2006 after appearing on Britney & Kevin: Chaotic, while model/actress Carmen Electra broke up with rocker Dave Navarro in 2006 after shooting 'Til Death Do Us Part: Carmen & Dave.
