The Ukrainian dwarf orphan who was abandoned by her American adoptive parents who accused her of being an adult masquerading as a child has broken her silence in her first televised interview with Dr. Phil.

Natalia Grace Barnett denied Kristine and Michael Barnett's claims in a segment that will air Thursday at 3pm EST. Natalia's new adoptive parents, Cynthia and Antwon Mans, joined her in the interview to share their accounts of her behavior after having lived with her for nearly seven years.

In clips of the interview obtained by DailyMail.com ahead of the broadcast, the self-proclaimed 16-year-old addressed the Barnetts' purported evidence that she is 13 years older than she says she is.

In one clip, Dr. Phil plays a video of Kristine alleging that she found clothing in Natalia's closet with 'at least some reminisce of a menstrual cycle' - which led the adoptive mother to believe she had gone through puberty.

Asked whether she was ever confronted about the findings, Natalia said: 'Christine did not say anything about bloody clothing or anything to me.'

Cynthia also denied the idea that Natalia had her period, saying: 'She's been with us for almost seven years, to this day she does not have a menstrual cycle.

Antwon added: 'Not one.'

Natalia Grace Barnett responded to her former adoptive parents' claims that she is an adult sociopath masquerading as a child in her first televised interview with Dr. Phil

In a second clip, Dr. Phil repeats Kristine's assertion that Natalia once tried to poison her adoptive mother by spraying bleach in her coffee while the pair were cleaning together.

He noted that Kristine has video she claims shows the moment the incident happened.

Natalia explained that she was polishing a spot on the table with Lemon Pledge and had moved the coffee out of the way when Kristine came over and asked what she was doing.

'She claimed I tried to spray it in her coffee, you can look in her coffee - there was nothing,' she said.

DailyMailTV first broke Natalia's extraordinary story after the Barnetts were arrested for child abuse in September.

Six years ago, in 2013, they left Indiana for Canada with their other children but they left Natalia behind. She said at the time that she was nine.

However they had become convinced she was actually 22 and was a sociopath adult who had masqueraded as a child for years and tried to kill members of their family.

They had adopted her three years earlier, in 2010, under the impression that she was a six-year-old orphan.

Now, the pair are awaiting their next court date and the issue of whether or not Natalia is an adult or child continues.

She insists that she is only 16. She is now living with another Christian American family who took her in after the Barnetts left her.

Kristine and Michael agreed to the emergency adoption of Ukrainian-born Natalia Grace in May 2010. The photo above shows Natalia in September 2012. Her original birth certificate made her nine but a court would later determine she was in fact 23 when this picture was taken

In her first on-camera interview, airing Thursday afternoon, Natalia shared her side of the story

In her first on-camera interview, she told Dr. Phil how the Barnetts were lying.

'It's not true!' she insisted when asked about their claims that she had pretended all along to be a child.

She was joined for the interview with her new adoptive family.

'It's not true at all. I just want people to hear my side,' Natalia said.

She and her new adoptive mother, Cynthia, also insisted that a bone scan she underwent after they abandoned her proved that she was the age she says she is.

The Barnetts said they had her go through bone scans which suggested she had been born in 1989.

Cynthia also said that despite Natalia's first adoptive family's allegations, she and her husband did not worry about bringing her into their home to mix with their other children.

'We're supposed to help. Me and my husband adopted these kids.

'It's like, who would do it if you don't?'

The Barnetts claimed they were living a real-life version of the horror film Orphan, in which a good-willed American couple hire a foreign orphan only to later discover she is a sociopath hell-bent on killing their family.

They claimed that Natalia tried to kill them and their sons.

They left her in an apartment in Indiana - three years after adopting her - where she says she fended for a year until the police discovered her and her story.

The Barnetts' story is that they adopted a teenager in 2010 who came to them with pubic hair and periods.

They say she stood over them as they slept and drew pictures depicting her murdering their whole family.

She smeared blood on walls and mirrors and, Kristine claimed, tried to electrocute her on an electric fence.

Far from abandoning her, they say they set her up in a paid-for apartment after buying her clothes and furniture and making sure she had food stamps.

They went to Canada not to get away from her, they say, but for one of their other children to pursue his education.

They have called the allegations against them 'devastating'.

'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', said Kristine Barnett of her adopted daughter Natalia (pictured)
