Vicki Gunvalson wants to move on. The Real Housewives of Orange County star spoke to exclusively about why she filed for divorce from husband Donn on Monday.

"We tried," Vicki, 48, told Us. "It's just too hard on both of us."

She added: "It is amicable and we want to keep this as private as possible."

Gunvalson also addressed the split on her official Facebook page.

"Donn has been an important part of my life and he will continue to be," she wrote. "I would like to thank all of you for the outpouring of love and support that we have received."

Vicki and Donn wed in 1994; although they have no kids together, her children from her first marriage, Michael and Briana, lived with them in their home.

In attempt to rekindle their romance, the pair renewed their vows during a tropical getaway in July 2009 in a sweet ceremony filmed for the show.

Vicki, a life insurance mogul, told Us that she's currently filming the sixth season of Real Housewives of Orange County. Featuring two new housewives, Peggy Tanous and Fernanda Rocha, it should air on Bravo toward the end of this year. (Castmate Lynne Curtin will not be returning.)
