Gunvalson's marital woes have been chronicled on The Real Housewives of Orange County for several years.
In 2008, the show's fourth season included a storyline in which Gunvalson -- who has two adult children from her first marriage but none with Donn -- said her "love tank is depleted" and stated she was unsure whether her husband could "fill it up."
The couple later renewed their vows in a June 2009 ceremony that was featured on The Real Housewives of Orange County's fifth season, however Gunvalson had suggested the couple was having problems again during March's broadcast of the season's reunion show.
