This undated publicity photo provided by Bravo shows, from left, Heather Dubrow, Tamra Barney, Vicki Gunvalson and Gretchen Rossi, in a scene from "All Housewives Clam Bake at Rachel's" in Bravo's Season Eight of "The Real Housewives of Orange County." The TV series creator Scott Donlop, who cast Gunvalson, remembers her apprehension about joining the show like it was yesterday. At that point, nobody had any inkling "The Real Housewives" would last for eight seasons, let alone ignite a cultural phenomenon. (AP Photo/Bravo, Vivian Zink)
