Not only did Courtney Robertson sniff the roses, she drank the Kool Aid.

The Los Angeles model says that "in many ways, she felt brainwashed" into falling for the show's lead suitor Ben Flajnik during the two months-plus she filmed the ABC dating show.

"You're so closed off," she told US of the taping process, in which contestants are forbidden from watching TV or checking social media.

Courtney said that the nice guy winemaker Ben portrayed himself as -- in front of the cameras -- was all a façade, noting a gesture the Romeo made on the show when he gave her her favorite snack, popcorn.

"I realized it wasn't him who had the idea … it was the producer," Courtney said.

Once the show was over, Ben ditched the romantic schtick, on one occasion telling the stunning 29-year-old he was "all picnicked out."
