Ramona Claims LuAnn’s Husband Cheated AGAIN One Year After Affair

LuAnn de Lesseps recently married fiance Tom D’Agostino in a fairytale ceremony — but he’s still up to no good, her frenemy Ramona Singer claims.

On the season premiere of the Real Housewives of New York, divorced mom Singer, 60, dropped a cheating bombshell on her on-off pal over dinner.

“If something happened in May, would you want to know about it?” the pot-stirrer asked the former Countess, who was devastated when costar Bethenny Frankel caught her man sucking face with another woman on camera last season.

Singer, who once dated D’Agostino and was infamously cheated on by ex-husband Mario, then claimed the businessman’s ex-girlfriend said that he kissed her and called her constantly while engaged to de Lesseps, 51.

But the bride-to-be brushed off the talk.

“They’re still friends,” she explained.

When Singer accused her friend of turning a blind eye to the betrayal, de Lesseps defended her relationship.

“I know what I have!” she snapped. “I’m not going to listen to the fodder of all you girls anymore... I’m a big girl and I know what I’m doing.”

As RadarOnline.com readers know, de Lesseps went through with the New Year’s Eve wedding in Palm Beach, and is still standing by her man’s side. But will the marriage last?

Meanwhile, Frankel, 46, celebrated the long-awaited end of her tumultuous marriage by selling her Tribeca apartment, where her ex lived against her wishes during the never-ending divorce process.

“It’s been a source of disgust and anger,” she said of her former home. “We need to sell this apartment and close this chapter.”
