'Real Housewives of New Jersey' star Danielle Staub has had to file a restraining order against her current fiance, Oliver Maier's ex-girlfriend.

According to PEOPLE, Danielle and Oliver filed paperwork for the order in an Englewood, New Jersey courtroom on Tuesday, seeking to prevent Gina Curko from contacting or going near them.

A source close to the couple told the entertainment outlet that Curko has been attempting to get back together with Maier and has been verbally harassing both of them. Page Six also reports that documents say Curko threatened to kill the couple.

But a source close to Curko is denying the allegations:

“It’s all lies,” the source says. “Oliver has been the one trying to get back with Gina, not the other way around. She’s happily reconciled with her husband. Danielle is just trying to staying relevant and on the show and trying to cling on to this relationship.”

“She and Oliver have been the ones harassing Gina, not the other way around,” the source continued to PEOPLE.
