A former beauty queen and educator in New Mexico who appeared on the hit television show “Better Call Saul” was arrested after hitting her fiancé and his son during an argument that erupted when her own son used her work computer to watch porn, police said.

Annittra Atler, 46, of Albuquerque, was arrested Sunday at her home after her fiancé, Patrick Ficke, told cops the special education principal for Albuquerque Public Schools “beat [him] up” and left an abrasion on his left forearm after learning that her son, Shawn, was watching porn on her work computer, according to a criminal complaint obtained by The Post.

“Patrick said he got upset at the situation and told Annitra her son was ‘acting stupid,’” the complaint reads. “He said Annitra then got upset and began to push him.”

Ficke told officers that the assault took place in the couple’s bedroom, near a small dog crate, adding that he was possibly hurt as he fell to the floor. The altercation ended when Ficke fell, he said, and his son, Aiden, witnessed the entire attack, according to the complaint.

Ficke then called his son’s mother to ask her to pick him up from the home.

Atler, meanwhile, told responding officers that she and Ficke drank wine during dinner and then got into an argument when Ficke found porn on her work computer that her son had just been using. But Atler denied the dispute ever got physical, police said.

The mother of Ficke’s son — who was identified by police as Veronica Lewandowski — later told police that Ficke called her earlier to say that he had been assaulted by Atler and that she should come pick up their son.

“She then went to their residence and picked up Aiden,” the complaint continued. “Veronica told me that Aiden said he saw Annittra hitting his dad. Aiden was also in the room and tried to intervene, when Annittra slapped him with her left hand across his right cheek.”

Ficke’s son, who not seriously injured, told police that his father had found “bad things” on Atler’s work computer, which had been recently used by her own son, Shawn.

“He said his dad and Annittra began to argue as Annittra was cussing at Patrick,” the complaint continued. “Aiden said he saw Annittra hitting his dad in their bedroom with closed fists.”

Ficke’s son told police that Atler hit his father five or six times before she turned around and slapped him, which she later denied, police said.

“She said Aiden disrespected her by calling her a monster,” according to the criminal complaint.

Messages seeking comment from Atler — who played the wife of a businessman named Dale during Season 2 of “Better Call Saul” in 2016, according to her IMDb profile — were not returned Tuesday. Atler is also a former beauty queen who won a national pageant called Ms. Woman United States in 2015, KRQE reported.

At the time, Atler was praised by the station as a role model for children in addition to her post as a principal at Abode Acres Elementary School. She advocated working against childhood hunger prior to taking home the pageant in Las Vegas.

“I have the most incredible staff in all of Albuquerque,” Annittra told the station in 2015. “And they’ve been so super supportive and really, really kind of put up with me with all of my nerves and my craziness throughout this year, so I’m really blessed and I can’t do enough to give back to them.”

A spokeswoman for Albuquerque Public Schools confirmed to The Post that Atler, who now works as a special education principal for the district, had been placed on administrative leave following her arrest.

“We don’t discuss personnel issues,” spokeswoman Monica Armenta said during a brief telephone interview when asked whether Atler would be disciplined or face termination following the allegations.
