It’s official: Bravo has pulled the plug on “The Real Housewives of D.C.” — the first time in “Housewives” history that an iteration of the reality franchise has not moved forward for a second season, reports the TV Column’s Lisa de Moraes. De Moraes chronicles the rise and fall of the D.C. housewives and answers the all important question: Is this the end of the road for Cat, Lynda, Mary, Stacie and Michaele? According to an e-mail exchange between TV Column staff and Bravo’s Andy Cohen, Cat Ommanney is slated for the network’s April 28 “Watch What Happens Live Royal Wedding Spectacular.”
