The producers of Bravo’s “The Real Housewives of New York City” are annoyed with the timing of Luann de Lesseps’ separation from Tom D’Agostino Jr. after seven months of stormy marriage — because the series had just spent a grueling 10 hours taping three reunion shows set to air at the end of the current season.

“They are going to have to reshoot,” one source told me. “Otherwise, the reunion shows will seem hopelessly out of date with Luann talking about how much she loves her husband and how they are working out their problems.”

While the timing was bad for Bravo, it was good for Luann. “This is the time of the year when they are figuring out the next season,” said my source. “Guess who will be the show’s biggest housewife now that she is single again and back on the dating scene?”

D’Agostino feels he was used by Luann, according to friends, but his only comment to me was, “There was real love there, and this was a real marriage.”

One friend of D’Agostino said, “He got played. It was all orchestrated. Without Tom, they wouldn’t have had a season, or the season before. And next season, it will be ‘reinventing Luann’ thanks to Tom. He should be getting a check.”

Luann is just the latest marital victim of the “RHONY” franchise. Ramona Singer, Jules Wainstein and Bethenny Frankel all saw their marriages implode while taping the show.

“Bravo just ruins marriages,” said my source.

A representative for Luann said, “She and Tom loved each other very much, and [the separation] has absolutely nothing to do with the show.”

“Tom loves Luann and wanted to be married, but he was expecting a different life,” said the pal. “He wanted someone to share his life with and do things with. He didn’t want to just be her escort to dinners and parties.”
