It’s hard for Vicki Gunvalson to not think of the past decade of her life in terms of TV seasons: She’s the only remaining original cast member on Bravo’s first “Real Housewives” series, “The Real Housewives of Orange County.” The 53-year-old said in a recent interview that she equates milestones in her life to what season they aired on. The show, which airs at 9 p.m. Eastern time on Mondays, is now in its 10th season. In an interview with the Associated Press, Gunvalson admitted that she’s made only a handful of real friends among the women on the show. She said, “You think about all these people I’ve filmed with all these years–and there’s not many I stay in touch with.”
