The adopted “girl” whose Indiana parents claim she is sadistic scam artist with dwarfism spoke to Dr. Phil in an interview set to air this week.

Natalia Grace Barnett, who allegedly plotted to kill her entire family, denied the allegations against her in the interview, which will air Thursday.

“It’s not true at all,” she told Dr. Phil, according to a short clip of the show. “I just want people to hear my side.”

The couple who adopted Natalia — Kristine and Michael Barnett, who have since split up — have claimed the “girl” is actually a Ukrainian woman who tried to poison Kristine and bragged about her plans to kill them.

“She would make statements and draw pictures saying she wanted to kill family members, roll them up in a blanket and put them in the backyard,” Kristine Barnett told the Daily Mail in September.

“I saw her putting chemicals, bleach, Windex, something like that, in my coffee and I asked her, ‘What are you doing?’” she added.

Kristine and Michael have both been charged with neglect for abandoning Natalia and moving to Canada in 2013, when Indiana authorities argue that she was still a child.

They have both said they’re innocent of the crime because they believe Natalia was actually an adult at the time.

In the teaser for Dr. Phil’s exclusive interview with Natalia, he asks her: “I guess it comes down to whether or not you are an evil psychopath demon child that’s come over here to murder everybody.”
