LeeAnne Locken is leaving the “Real Housewives of Dallas.” I know, who cares? But she is the last Preston Hollow resident on the show. We used to have Cary Deuber. Now the only housewives are in HP and the suburbs. Locken, 52, has been a full-time cast member for four years. Fellow cast members called her a racist. She called Kary Brittingham, who was born in Mexico, a “little chirpy Mexican.” Locken got grilled on the RHOD reunion show and called a racist by fellow cast-mates. Before all of the controversy, we profiled Locken here. Her dog is cute.
