The Real Housewives got an unwelcome dose of reality the other night after an unidentified man at a bar allegedly “roofied” a couple of the leading ladies, enticing Ramona Singer to urge fans: “Never take a drink from a stranger”, she tells RadarOnline.com exclusively.

News of the incident surfaced when Tamra Barney chatted with Andy Cohen on Bravo's Watch What Happens Live! last Sunday, claiming: "I got roofied,” referring to the date rape drug Rohypnol.
