Carole Radziwill Brings Up Luann's 'Addictions and Family Problems' Amid 'RHONY' Twitter War with Bethenny

The former "Real Housewives of New York" star announced late last month she would be leaving both the Bravo reality show and her "frenemies" behind. Soon after, Carole's former BFF Bethenny Frankel implied Carole had actually been fired -- and that fire is still burning.

On Monday night, Carole responded to a fan who tweeted, "The fact that Bethenny would even say that you were fired because she gave Bravo an ultimatum is bullshit. She said that because, for whatever reason, B sees you as some kind of competition. She's such an immature crybaby."

Carole replied, "People say the dumbest shit. But it actually sounds like something she'd do. I'm glad I'm not filming the show any longer. It took too much of my time and focus away from others things I wanted to do."

A fan then tweeted at Carole to let her know Luann de Lesseps -- who recently completed a second stint in rehab -- also implied she had been fired from the series during a recent cabaret show.

"I'm all good!" Carole replied to the fan. "Luann should focus on her own addictions and family problems. I wish her the best."

On July 25, Carole told People she was leaving the "Housewives" after Season 10 because she wanted to return to pursuing her original passions.

"After six seasons on Bravo's 'RHONY,' I have decided to return to what I do best -- journalism and producing," she said. "I am sure this does not come as a surprise to any of the viewers, all of whom have been supportive, encouraging and kind."

"My original curiosity about reality television has waned over the years, and I am focusing on TV and writing projects that better suit my more steady temperament," she continued. "I have worked with amazing producers, made great friends and I'm thrilled to leave frenemies behind. I will remember this entire experience with delight, humor and a veracious accuracy."

Days after, Bethenny took to Twitter to seemingly shade her former friend. Without calling anyone out by name, Bethenny wrote, "Bravo has reasons for not asking [Housewives] to return. It's based on research and focus groups and YOU. Aside from three years I left, no 'RHONY' cast member has ever quit. One saying they chose to depart and attributing it to me is fiction. It's healthier to be truthful about a hard situation."

She then said this:

Carole isn't the only one who took issue with that statement, as another former "Housewives" star, Heather Thompon, responded to Bethenny saying she did indeed choose to leave the show. "I left the show. I was not fired Frankel had zip zero to do with my decision," heather said. "She is certainly not the only housewife who left the franchise nor am I."

Radziwill re-tweeted that as well, adding, "Exactly. 🎤 See you next week. 😘"

"The Real Housewives of New York" airs Wednesdays at 9 p.m. on Bravo.
