It's been almost four years since Bravo first introduced the world to the residents of what is surely the country's most famous gated community, Coto de Caza, in the inaugural season of The Real Housewives of Orange County. The series has since taken on a life of its own, setting up posts in New York, New Jersey, and–as the Secret Service learned the hard way back in November–Washington, D.C. Now, it's been announced that the franchise will be moving to Beverly Hills. While the cast hasn't yet been confirmed, the names Kyle and Kim Richards have repeatedly cropped up. Both women have acted in film and on television (Kyle had a part on Beverly Hills 90201) but they are probably best known as the sisters of Kathy Hilton, mother to Paris and Nicky. And, if we learned anything from the New Jersey cast, it's that the inclusion of extended family members makes for great Real Housewives–we can only hope that Kim and Kyle's nieces will be open to some cameo appearances.
