As shown on Wednesday night's episode of The Real Housewives of New York City, Lesseps' engagement to D'Agostino is an awkward yet hot topic amongst all the ladies.
Frankel, 45, pointed out at the dinner table how her co-stars have had the tendency to pass the same men around, with D'Agnostino being one of them. Before proposing to Lesseps in February, he had been linked to both Housewives Sonja Morgan and Ramona Singer.
Lesseps, clearly frustrated by the facts, barked in the episode, "I don't give a flying leap. I don't care who f-cked who. I don't care."
In her Bravo blog, Frankel -- who had been accused of being jealous -- elaborated on the discussion. And in the process, she threw D'Agnostino under the bus again.
"I can say many things but one I am certain about is that no one is jealous of LuAnn's relationship with Tom," wrote Frankel. "At this point, we are really hoping it is real and that Luann is happy, but no one is jealous. Fact."
Frankel went on to remind fans that D'Agnostino has "been with" three people at the dinner table.
"I mean the Upper East Side is small, but Manhattan is huge. Something smells fishy. Why the rush? What is it with this guy swimming in one tiny fishbowl? I'm feeling my usual skeptical self," Frankel wrote.
