Bethenny Frankel Bashes Ramona Singer on 'RHONY Reunion Part 2' for Cheating Rumors [WATCH]

Grab some red wine, a pint of your favorite Ben & Jerry's and your best gal pals, because tonight's part two of the three part Real Housewives of New York City reunion just got CRAZY! Season seven of the Bravo series has been nothing but dramatic, but when these eight ladies, including Bethenny Frankel, Ramona Singer, Carole Radziwill, LuAnn De Lesseps and Kristen Taekman, got together to talk about the roller coaster ride that was the past 20 episodes, the drama hits an all time high. The gals rehashed the drama from the Turks and Caicos trip from hell, to the cheating rumors that Singer brought up about Frankel.

When the gals all reunite for part two, Frankel decides to clear the air regarding the false rumors that Singer was spreading regarding her first marriage. According to Us Weekly, Bethenny brought up the fact that Ramona was stating that she had allegedly cheated on her first husband.

"You have a cunning side to you," the starlet says to Singer. "You had said nasty things to a lot of people in this group about me that's not even true. It's unbelievable."

However, when Ramona refuses to own up to anything in the Bravo TV clip, Frankel goes on the attack to call her out in front of everyone.

"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]," Bethenny explained to Andy Cohen. "With God as my witness, I did not cheat on my first husband or my second husband."

When Singer explained, "This is what people told me," Frankel dug even deeper into her, telling her to "shut your f**king mouth, because you don't know what you're talking about. It's nasty!"
