Danielle Staub is back on “The Real Housewives of New Jersey” Wednesday, and discussion of her past sex tape makes its way into the series’ plot line.

Staub, 57, recently told Page Six that during an argument, her co-star Margaret Josephs brought up the X-rated recording. But Staub considers herself and the tape to be of a higher level than an episode of “RHONJ.”

“She decided to bring back to life a certain tape that was put out on me, and there’s only four of us icons that have one and it’s a sex tape,” Staub said. “I think the viewers will see more discussions on that.”

It is unclear exactly to whom Staub is referring, but Kim Kardashian, Pamela Anderson and Paris Hilton are the biggest Hollywood names whose sex tapes have been made public.

“Margaret tried to be relevant, bringing back to life something that she was never a part of it from the beginning,” she added. “Oh, that poor little Margaret … she’s gotta stay hyper-focused on Danielle’s life. Her obsession continues.”

Staub did not give any other details on the tape, but The Post reported in 2009 that Staub’s ex-boyfriend Steve Zalewski claimed to have recordings of them engaging in sex acts.

“The Real Housewives of New Jersey” airs at 8 p.m. Wednesdays on Bravo.
