During the reunion, as the two opened up about the breakdown of their friendship, Andy Cohen asked Dorinda: “What is your issue with Tinsley?”

“I believe half of what I hear in life and all of what I see. You guys saw just what was on the show. There was a lot of stuff that went on,” Dorinda said.

“What happened was, after [Scott Kluth and I] had broken up, when we were in Miami — this was season 11 — you and I got in this horrific fight that was not on camera because I had told you that Scott had generously given John [Mahdessian] (Dorinda‘s ex-boyfriend) some money that you did not know about,” Tinsley then shockingly revealed.

“I don’t know why we’re talking about John,” said Dorinda.

“The betrayal that you felt for John manifested to anger towards me. You took it out on me. You called John screaming,” Tinsley continued.

“It’s just not true,” Dorinda denied.

“The producers did not want me to stay in the house that night because you were going so crazy. They were worried for my safety. You turned on me that moment when you found out John had that money,” Tinsley revealed.

When asked if that was the real reason for their fallout, Dorinda said: “No, I didn’t even know about that.”

Viewers were then shown unseen footage from Season 11 of Dorinda confronting John about the situation.

“You don’t run game behind my back, ever. I don’t want you to talk to Scott. He’s not your friend. When I say to you don’t do something, you better f- well listen,” she was seen saying on the phone to John.

“I did nothing to you to make you hate me the way that you do. Your jealousy, your hatred, your obsession with my relationship. Hey, girl, I’m engaged. We’re getting married,” Tinsley said.

“With no financial security. Tinsley, I’d hate your life,” Dorinda added.

It was recently revealed that Tinsley is leaving RHONY for this reason. Dorinda is also leaving the franchise.
