A "Real Housewives of New Jersey" star was reportedly filmed by Bravo performing a sexual act following a night of heavy drinking during a cast trip to Atlantic City. But the footage will not be aired as the cast member involved in the raunchy scene threatened to sue the network if the tape saw the light of the day, a report said.

The raunchy scene was filmed when the ladies were asked to demonstrate the proper way to perform a sex act, a show insider told Radar Online, who added that "one of the housewives really rose to the occasion" and volunteered to perform it.

The housewife even dished out about her sex life with her husband, and is said to have shared intimate details about the games she plays in the bedroom.

"She alluded to the fact that one of the games she and her husband play in the bedroom involves a strap on," said the source. "The rest of the girls sat shocked, refusing to partake in any of the sexual demonstrations."

Upon returning from Atlantic City, the housewife told her husband what happened, and he was livid, the source explained.

He "immediately phoned Bravo threatening to sue them for defamation of character and slander should this footage ever be shown. Bravo, likely not wanting to deal with the courtroom drama, opted to shelve the footage," the source said, joking that "Maybe one day viewers will get lucky, and the footage will end up in an adult video store!"

The identity of the cast member has not been revealed, but that hasn't stopped fans from speculating who the housewife could be. A good number of fans have their bets on Amber Marchese, as Dina Manzo had confessed to sharing sexual secrets with Marchese, and also because Dina had asked Amber "to shove it up his ass" during the 'First Responders' party.

Manzo also wrote on her blog about sharing bedroom secrets with Marchese: "At this point in our relationship there was so much sexual talk between us girls that you didn't get to see. You know chicks get together, open a bottle of wine, and the giggles begin. Amber had shared some of her hysterical stories of shall I say…taking over in the bedroom with us, and I would tease her endlessly."
