"Real Housewives of New York" star Ramona Singer says she was recently drugged by an unidentified man while visiting a bar with other cast members. 

Speaking to RadarOnline about the incident, Singer said she's now urging fans to "Never take a drink from a stranger."

News of the incident surfaced when Orange County "Housewife" Tamra Barney spoke with Andy Cohen on Bravo's Watch What Happens Live! Barney claimed she got "roofied," referring to the date rape drug Rohypnol.

The reality stars from both coasts -- including Orange County's Vicki Gunvalson, Barney, and newcomer Peggy Tanous, met up with Ramona at a bar in New York City a few days ago.

Ramona said that before the group left the bar, a middle-aged man came over with drinks in his hand. "He sat next to Tamra and Peggy and said, 'I have a special drink for you two ladies.' 

"Tamra drank only part of her drink, but Peggy drank all of it, poor thing. We all left as they finished their drinks and they got back to their hotel 20 minutes later and felt the effects," Ramona said. "Thankfully, Vicki was there because they almost had to go to the hospital."
