The truth comes out! In the second part of the epic Real Housewives of New York City Season 7 reunion, Bethenny Frankel confronts Ramona Singer about rumors she'd spread regarding the returning Housewife's fidelity in both of her marriages.

 

"You have a cunning side to you," the Skinnygirl mogul tells her costar in Us Weekly's exclusive sneak peek at the episode. "You have said nasty things to a lot of people in this group about me that's not even true. It's unbelievable."

Ramona tries to defend herself, saying she brought up a fact, but Bethenny won't let her continue. "That's not a fact," she says.

But when host Andy Cohen asks Ramona to repeat what she'd said about Bethenny, she refuses. "I'm not going to go there because it's clearly making her upset, whether it's true or not," Ramona says, much to the chagrin of her costars who are upset that she won't "own up."

 

Bethenny tells the group instead. "What Ramona Singer said is that I cheated on my first husband and that [she] knew that to be true and [she] said it to [Heather Thomson]," she says. "And with God as my witness, I did not cheat on my first husband, or my second husband."

Interjects Ramona, "This is what people told me."

Yells Bethenny, "Well shut your f---ing mouth, because you don't know what you're talking about. It's nasty!"

Find out whether Ramona owns up to her mistake or not in Us Weekly's sneak peek, and tune in to the second part of the RHONY reunion on Tuesday, Aug. 25, at 8 p.m. ET on Bravo.
