DNA test seemingly confirms real age of adopted girl accused of being 22-year-old woman

A DNA test has seemingly confirmed the real age of Natalia Grace whose adoptive parents accused her of being an adult with dwarfism.

Ukrainian orphan Grace was adopted by Kristine and Michael Barnett in 2010.

In the first season of iD documentary The Curious Case of Natalia Grace, released earlier this year, the Barnetts accused Grace of being a 'sociopathic' adult with dwarfism who masqueraded as a minor.

However, Grace's real age has since been revealed.

In the first doc, the Barnetts alleged they had 'evidence' Grace was older than six years old when they first adopted her.

However, in the latest documentary - The Curious Case of Natalia Grace: Natalia Speaks, which aired on 1 January - Grace has hit back at her adoptive parents and taken a DNA test to get to the bottom of her real age once and for all.

So how old is Grace really?

Grace took a blood test - conducted by medical lab TruDiagnostic - in August last year.

At the time of taking the test, Grace believed she was around 20 years old.

However, the DNA test revealed that at the time of taking the test, Natalia was actually around 22 years old.

This means, in 2010, when she was adopted by the Barnetts, she wasn't six, but nine years of age.

Nevertheless, it proves she was still a child and not an adult masquerading as a child like her adoptive family accused her of being.

And it also matches up with an x-ray performed by a dentist when Grace was living with the family, the scan showing her teeth coming in as you'd expect for a child around eight or nine years old.

Grace reflects on the results of the DNA test: "This one little piece of paper throws every single lie that the Barnetts has said right into the trash with a match.

"This is so big. Because literally, this has been 13 years of just two people lying their butts off. They ruined a kid’s life. They painted [me] as some big monster.

"It just proves that I was not lying about my age. They ignored everything that was pointing to the truth just so they could create this stupid lie. They knew it and they still did what they did."

As well as accusing Grace of being an adult posing as a child, the Barnetts also alleged she tried to hurt their family - such as poisoning Christine's coffee.

Neighbors also spoke out in the first the documentary, accusing her of hanging around 'all the older, real old guys a lot' and 'talking sexual things to them'.

Grace has denied all of the accusations.

THE CURIOUS CASE OF NATALIA GRACE: NATALIA SPEAKS will premiere across three consecutive nights on ID beginning Monday, January 1, airing nightly from 9-11PM ET/PT
