How do you ruin drag queen bingo? Invite The Real Housewives of New York.

Season 12 of RHONY ended with a bang after the ladies arrived at Sonja Morgan’s drag queen party. Newcomer Leah McSweeney innocently tried to give a toast thanking former castmate Tinsley Mortimer — who announced she was leaving the franchise earlier this year — for her time on the show.

But Dorinda Medley wasn’t having it. “No. I’m not doing that s–t,” Medley said as she interrupted McSweeney. “F–k you.”

The newcomer fired back with, “Are you f–king kidding me?”

“Sorry, I’m not a part of that,” Medley responded.

“I will not give Tinsley that. F–k you. I won’t,” the 55-year-old added. “Tinsley almost ruined our show. You’re going to give a toast to Tinsley, who left the show and breached her contract and left over nothing. You don’t mention her name.”

McSweeney tried to explain herself to costar Luann de Lesseps, and the countess quipped that Medley needed to “grow” as a person.

“This is beyond my wildest expectations of [Medley] as a person,” de Lesseps told McSweeney. “She’s got work to do. When you don’t grow, that’s a great example over there. There’s a lot of pain and a lot of s–t going on in there.”

Mortimer traded in the Big Apple for the Windy City as the RHONY socialite left the franchise to move to Chicago to be with her fiancé, Scott Kluth.

“Thank you from the bottom of my heart to all my fans and friends who supported me and are happy for my fairy tale ending,” the 45-year-old wrote on Instagram in a heartfelt note to her fans. “Without #RHONY, I would never have met my prince charming, Scott.”

Coincidentally, the finale was filmed before Medley was shockingly fired from the hit Bravo show after six seasons on August 25. “What a journey this has been. I have laughed and cried and tried to Make it Nice,” she captioned a photo of herself on Instagram referring to her iconic catchphrase.

“But all things must come to an end,” she continued. “This was a great outlet for me to heal when my late husband Richard passed away. I have met so many interesting people and learned so much about myself, about life and about women along the way.”

RHONY has lost two of its iconic ladies as of late, and who’s next is anyone’s guess. OK! exclusively reported that reality star Bethenny Frankel is “meddling behind the scenes” and determining who stays and who goes.

“Bethenny is like the wicked witch that won’t die. She left the show… She is still having private meetings with the show’s boss, Andy Cohen, out in the Hamptons and isn’t shy about telling him who should stay and who should be fired,” sources told OK!

OK! also exclusively reported that former E! host and current Daily Mail TV correspondent Alicia Quarles will be joining the hit Bravo franchise for its 13th season to “increase diversity.”
