Twisted killer Scott Peterson is locked in a jailhouse love triangle with his longtime pen pal and monster mom Casey Anthony, The National ENQUIRER has exclusively learned.

The bizarre catfight kicked off when Casey (pictured below in 2017) — who skated on charges she murdered her two-year-old tot in 2008 — sent a letter to wife-killer Peterson about her desire to put out a book to tell the stories of the “wrongfully convicted,” a source told The ENQUIRER.

“Casey wrote him a letter asking if she could visit him. I don’t know what she is trying to accomplish by doing that,” said the source.

But the 47-year-old convict’s galpal got wind of Casey’s note and confronted Peterson (pictured below in 2003), who is serving life behind bars in California’s San Quentin prison for murdering his pregnant wife, Laci, and their unborn son, Conner, on Dec. 24, 2002.

“[The pen pal] was really upset he was going to communicate with this crazy woman,” the source reported.

Peterson’s jealous pal warned him to stay away from “America’s Most Hated Mom,” according to the insider.

As The ENQUIRER previously reported, notorious party girl Casey spun a web of lies about daughter Caylee’s death in Orlando, Fla., before being acquitted of murder in a controversial trial.

Casey was ultimately found guilty of providing false information to law enforcement officers and walked out of jail ten days later in 2011 after being credited with time served.

Shockingly, sources said self-proclaimed photographer Casey, now 33, has been pining for sicko Peterson’s attention for years!

“In her twisted mind she identifies with Scott because they share the same egocentric obsession with sex and partying,” New York psychologist Dr. Judy Kuriansky told The ENQUIRER. “He killed his unborn child, so he could be free to have his affairs and she’s allegedly done the same thing.”

“She sees herself as his equal, an attractive sexual person who has been wrongly accused and punished. She believes this fantasy of her and Scott being together to be real. It gives her a sense of power and connection,” said Kuriansky, who has not treated either Peterson or Casey.

A San Quentin snitch told The ENQUIRER Peterson has been captivated by Casey after seeing news coverage of her case on the small TV he’s allowed in his cell — but the jailbird’s loyal galpal nixed his prison meetup with her!

“He may have received a letter, but she won’t let him ever see her,” the source squealed.
