RHONY's Luann D'Agostino Says Tom 'Definitely' Did Not Cheat On Her

The Bravo reality star has announced that she and Tom are getting divorced after just seven months, but she told Page Six on Friday that his past issues with fidelity were not a factor.

"I do not think Tom cheated on me, definitely not," she said. "God knows he's got himself in some trouble in the past, but I don't believe that continued [while we were married]."

She continued, "It was impossible, we were having problems and we tried really hard to fix things, and we finally came to the conclusion it was just not going to work. It was a tough decision and we are both very sad about it. But the truth is we just weren't getting along."

On Thursday, Luann confirmed rumors that had been swirling for several weeks, announcing on Twitter: "It's with great sadness that Tom & I agreed to divorce. We care for each other very much, hope you respect our privacy during this sad time!"

Sources told Page Six that in the last week she'd invited her French ex Jacques Azoulay to her home in Sag Harbor, which prompted Tom D'Agostino to file for divorce.

She dated Azoulay for four years and he was featured on "Real Housewives," but she insists they're just friends now.

"Jacques has a girlfriend and he's staying in a hotel, we're friends, he's not staying at my house. There's no truth to the story of Jacques and me. God knows I've been going through enough recently, I don't understand why this false rumor is coming at me."

Luann denied the two were heading for divorce just last month, during an appearance on "Watch What Happens Live." Confronted by Andy Cohen about a Page Six article claiming their marriage was "hanging by a thread" after she slapped D'Agostino in a restaurant, Luann insisted, "It's gossip. Come on, it's gossip."
