A businesswoman is suing 'Real Housewives of New York' star Carole Radziwill in an effort to block an episode of the reality show that will cause the woman 'irreparable harm,' and is supposed to air tonight.

Barbara Kavovit, a former contractor who started a line of tools for women called DIYVA, is claiming that Raziwill secretly taped what she thought was a private conversation in December of 2016.

She filed the papers Wednesday in Manhattan Supreme Court seeking an emergency order to block an episode of the reality show from airing the same night.

Details of the conversation were not included in the emergency filing, but Kavovit's lawyer hinted in court that the conversation had already caused drama among the Housewives, reported the New York Daily News.

'Knowing what I know now I wouldn't have invited you to my wedding,' one unnamed star texted Kavovitz, according to her attorney.

The only wedding featured or talked about on the show since Bethenny Frankel's nuptials in 2010, is Luann de Lessepps, now Luann D'Agostino.

'Knowing what I know now I wouldn't have invited you to my wedding,' one housewife, perhaps Luann de Lesseps, texted Kavovitz, according to her attorney. Last season on the Real Housewives of New York, it was revealed that Luann's fiance, Tom D'Agostino, had cheated her shortly after they got engaged. They married New Year's Eve despite the transgression

She married Tom D'Agostino, who was caught cheating last year, on New Year's Eve in Florida.

Shortly after they were engaged, photos emerged of him making out with a mystery woman, which were texted to Frankel.

The photos were shown last season, but Luann went ahead with the wedding and the person who took the photos was never revealed on air by Frankel.

Kavovit was at a charity event with Radziwill at Bagatelle, a restaurant in the Meatpacking district of Manhattan, on December 7, 2016.

She claims although she knew 'RHONY' was filming an episode at the party, she thought they would have some privacy when they stepped aside to chat.

'At approximately 10pm in the corner of the restaurant and away from any filming activities, she had what she believed to be a private conversation with an individual known as Carole Radziwill,' the emergency Manhattan Supreme Court Suit says.

'Unbeknownst to her, Ms Radziwill was wearing a microphone and this conversation was recorded,' the papers continue.

Then, more than a month later, in late January the two talked again over the phone for 30 minutes, and that conversation was also recorded, it is claimed.

Kavovit claims that Radziwill (pictured on April 5) needed her permission to be taped, despite the fact that New York state law only requires consent by one party

As soon as Kavovit hung up the phone, Radziwill called her back and let her know that both of the conversations had been recorded for the show, the lawsuit says.

Kavovit claims that Radziwill needed her permission to be taped, despite the fact that New York state law only requires consent by one party.

The businesswoman is asking a judge to ban the show from using her 'likeness and/or voice in any manner.' She says that she will suffer 'irreparable harm' if it airs.

She also requests that, from now on, the Real Housewives are prevented from using her likeness and/or voice on any episodes 'to air at any time in the future without her express written consent.'
