Ramona Singer Fears Eboni K. Williams Will Frame Her as Racist on 'RHONY' Reunion

Ramona Singer's apprehensive about the 'Real Housewives of NYC' reunion taping, because she believes Eboni K. Williams is going to try to make her look racist ... TMZ has learned.

Sources close to production tell us ... Ramona recently went to 'RHONY' producers to express her concerns about potential racial talks during the reunion -- specifically, that Eboni might attack her and frame her as a bigot.

We're told Ramona attempted to negotiate terms in order to avoid topics such as race during the Bravo special, but producers shot that down and said they'd never agree to that.

Our sources say Ramona accepts that, and has no plans to dodge the reunion -- she just wanted producers to know how she feels.

Of course, there's been a lot of drama surrounding the reunion already ... as it was scheduled to film in early August, but got bumped to September. Fans are speculating it's either due to low ratings or strife among the cast, but we're told it's simply due to "scheduling conflicts."

We broke the story ... Eboni fired back at those blaming the ratings slide on her race convos, saying it's on producers to decide what makes the final cut.

Eboni also appeared to throw shade toward her fellow housewives Thursday, when she posted a photo of her and Crystal Kung Minkoff -- the first Asian-American housewife on 'RHOBH' -- and wrote, "These deranged bigots are just mad AF that their days of dominance are coming to an end."

She included the hashtag #TimesUpOnWhiteSupremacy too, but didn't call out anyone by name.
