LuAnn de Lesseps won’t stand for any of her “Real Housewives of New York City” co-stars bashing her man. Tom D’Agostino found himself in the hotseat during Season 8, when it came to light that he’d dated two of LuAnn’s co-stars and cheated on her during a night out.

Tom is still a hot topic among the ladies who star on the Bravo show, and LuAnn is over it. The former Countess tweeted that she wanted the cast to “move on,” claiming that she and Tom had. LuAnn then directed a message to Ramona Singer, one of the main skeptics, telling her there is “#nothing to know” about her and Tom’s relationship.

This isn’t the first time LuAnn’s taken on Ramona or her other co-stars to defend her now-husband’s honor. In an interview with Fox News, the “Girl Code” singer called her former friend “obsessed.” She went on to say that Ramona needs to mind her own business.

“She’s obsessed with my love life. Get your own love life. Stay out of my love life if it’s not going to better my life. I don’t go after about the man she’s dating or about her past or divorce...So I feel like she should stay out of my business. I’m a grown woman, I make my own decisions. I’m secured and confident in my decision and in my relationship. That should be enough. And as a friend, she should respect that.”

LuAnn has also had to confront “RHONY” co-star Sonja Morgan over her salacious claims about Tom. The pair sat down during Season 9, episode 2 to discuss comments Sonja made to the press about LuAnn’s new marriage failing. Sonja stood her ground when asked about a statement she made suggesting that LuAnn and Dorinda Medley were at odds over the singer/socialite meeting Tom in the first place.

“Yeah, what kind of friend introduces you to a player like that?” Sonja asked, refusing to back down (via ET Online). “She knew! She knew what he does. He goes out with very young, tall girls, or he goes out with washed-up play-bunnies.”

There’s more Tom drama where that came from! Tune in to “RHONY” Wednesdays at 9 p.m. EDT on Bravo.
