'RHONY' Star Luann de Lesseps Sued by Ex-Husband and Her Kids Over $8 Million Dollar Home Sale

"Real Housewives of New York" star Luann de Lesseps has been hit with a lawsuit by her own kids and her ex-husband who claim she screwed them over in a house deal.

According to court documents obtained by The Blast, Alexandre de Lesseps claims the judgment in their divorce called for him to hand over the deed to their marital home in Bridgehampton, New York.

Alexandre claims the home was supposed to be put in a trust where the couple's two kids, Victoria and Noel, each would have half of the interest.

But Alexandre claims Luann violated the deal by never creating the trust. Her ex-husband and the kids claim Luann sold the home for $8 million and used the money to purchase a new home nearby for $3.1 million.

However, per their deal, if she sold the home and bought another the kids were suppose to have an ownership interest ... but that never happened. Alexandre claims Luann has threatened to sell her new home on the cheap and leave Suffolk County and buy herself a luxury home in upstate New York.

They are suing to block Luann from being able to sell off the home and for her to follow the terms of their divorce agreement.

The case is ongoing.
