Interesting. Natalia does seem believable here. The Barnett’s have always seemed off to me (especially Christina).Here's the episode:
As far as her living alone for a year, it’s not completely implausible. I’ve seen plenty of kids from dysfunctional homes that have had to cook, clean, etc. on their own due to absentee parents.
I realize the story sounds iffy on both sides, but we will probably never know the truth. I’m hoping the woman claiming to be the bio mother is DNA tested, even though it won’t prove anything if she’s not the mother because she will just be labeled a fame seeker.
