Family Feud: Luann De Lesseps Alone As Ex & Kids Cut Her Off Amid Lawsuit

Luann de Lesseps is now isolated from her family and friends amid her nasty new lawsuit, RadarOnline.com can exclusively report.

Though the Real Housewives of New York star, 53, bragged about hanging out with her children over the July 4th holiday, in reality, Victoria, 23, and Noel, 21, “have cut her off,” a source told RadarOnline.com.

Now, as she builds her brand as a cabaret singer, de Lesseps is “hanging out with a whole new theater crowd,” the source continued.

“She has cut ties with the Housewives, and now only wants to hang out with Broadway types.”

The singer’s old pals “don’t even recognize her anymore,” the source insisted.

As RadarOnline.com reported, de Lesseps’ two children and ex-husband Count Alexandre sued her for allegedly violating the former couple’s 2009 divorce agreement.

They claim she never set up a trust for the kids with money from the sale of their Bridgehampton, New York mansion, and instead bought a new home in Sag Harbor.

Now, she’s selling the Sag Harbor home — and her family is asking a judge to block her from offloading the property.

She’s also still in legal trouble stemming from her December arrest for allegedly resisting arrest and punching a police officer while intoxicated in Palm Beach. (She will return to court later this month to accept a plea deal.)

Even her love life is full of drama. After her split from husband of under a year Tom D’Agostino, De Lesseps is currently dating her manager Rich Super — who is still legally married!
