Vicki Gunvalson is joining the ranks of 'Housewives' stars who aren't really housewives.

Gunvalson filed for divorce from her husband of 16 years, Donn Gunvalson, TMZ reports.

The 'Real Housewives of O.C.' couple have no kids -- Vicki has two children from her first marriage.

"Everyone's doing OK. I mean, my mom and Donn haven't been spending much time together. They're just not really enjoying each other's company anymore. So it doesn't really bother me," her son Michael told
