'Real Housewives of Orange County' is the oldest running 'Real Housewives' of the franchise. However, its cast has received the biggest shake up going into season 15. "OG of the OC" Vicki Gunvalson and Tamra Judge will no longer be returning after being on the show since season 1. While not every returning housewife has been confirmed, fans now can rejoice to know that Kelly Dodd is 100% returning as reported by HollywoodLife. Kelly Dodd became a fan favorite last season after being targeted by the Tres Amigas and vowing to work on anger management.
