Joey Buttafuoco, Amy Fisher and Mary Jo Buttafuoco — the Long Island love-triangle figures who exploded onto the nation's front pages 15 years ago — plan a TV reunion they promise will have "shocking revelations," The Post has learned.

A California producer said he signed all three this month and hopes to sell their TV tell-all this year.

"Time heals all wounds," said Fisher, the erstwhile Long Island Lolita.

"It's been nearly 15 years, so it's time to just put it behind us. We played this all out in a public eye. It'd be interesting to let the public see the healing process at the end. They saw everything else — why not let them see the final product?"

Fisher, now 31, was convicted of shooting lover Joey's wife, Mary Jo Buttafuoco, in the head in 1992, and served seven years in prison. She was released early, with the magnanimous support of her victim.

Joey and Mary Jo ended their 26-year marriage in 2003. Joey has since remarried, and Mary Jo is engaged.

TV executive David Krieff said Mary Jo was the last one to sign off on the deal. She and her agent, Sherri Spillane, could not be reached for comment over the weekend.

"[Mary Jo] was the most hesitant for obvious reasons, since she was the victim," Krieff said. "I'm eternally grateful that Mary Jo has been so sincere in helping me along in this process."

Except in court during Fisher's trial, the three have not been in the same room together.

Fisher knows she'll be a bundle of nerves meeting face-to-face with the married man she once loved and the woman she nearly killed.

"[I'll be] scared, nervous, anxious. I'm sure I could think of 10 more words," Fisher said. "I probably won't be able to hold down my meal for two days before."

Joey and Amy are staying tight-lipped on the details they plan to reveal, but he promised fireworks.

Buttafuoco said he'd grill Fisher and ask: What drove her to knock on his family's Massapequa front door on May 19, 1992, and fire a bullet into his wife's head?

"I've never heard the answers to my questions. I've been asked about a million times by Mary Jo, 'Why did Amy shoot me?' I was never able to get that answer," said Buttafuoco, 49.

"You know something? There's going to be a lot of shocking revelations, and that's why I'm excited to sit down to do this."

Krieff said he'd like to tape, sell and air the show by May — in time for a TV-ratings sweeps period and the anniversary of the shooting. But he could be looking for some help from the justice system. Joey, who did time last year for auto-insurance fraud, is facing new charges in Los Angeles that he violated parole by possessing shotgun shells, forbidden for convicted felons.

Buttafuoco, who is free on bail, and prosecutors are still in plea-bargain talks.
