Watch 'Real Housewives of New York' Star Luann de Lesseps Confront Her Fiance About Cheating


Uncool, Tom D’Agostino. On Wednesday night, Real Housewives of New York fans will finally see the moment this season has been building up to: Bethenny Frankel revealing photos of Luann de Lesseps’ fiancé kissing another woman just days after he
and de Lesseps got engaged, and the Countess confronting D’Agostino with the news.

In a new clip, de Lesseps is seen making a phone call to D’Agostino from a hotel in Miami, Florida, where the ladies were on a girls’ trip.

“How could you do this to me?!” she yells. “At The Regency, in front of everybody! The whole town knows about it now!” Luann says, referring to the New York City hotel bar where D’Agostino was seen kissing another woman.

In another snippet
from the explosive finale, the women are back in NYC, and Frankel says she’s reached out to de Lesseps “several times” to no avail. “I’m wondering if now all of a sudden I’ve become the devil to her,” she says. “I’m thinking Luann doesn’t like the way this looks.”

There will be plenty more drama in the season finale, but we do know de Lesseps and D’Agostino are still engaged today and planning their wedding.

At an interview in her home in the Hamptons earlier this month, Frankel told ET she hasn’t seen de Lesseps at all this summer. “Luann and I are nowhere today,” she says of their relationship. “I hope that's she's happy. I really do wish her well. I hope that she will get there. I hope she will get married.”

“I think that Luann and people are more focused on how I used this information versus the fact the information itself existed,” she adds.

The Real Housewives of New York season finale airs Wednesday night on Bravo. To find out why Frankel might not return after this season, watch ET’s exclusive interview with her below.
