The feud is getting nasty.
After the mother of Farrah Abraham's late baby daddy, Derek Underwood, slammed her to RadarOnline.com for keeping little Sophia away from their family, the Teen Mom OG star accused her 6-year-old daughter's paternal grandmother of "stealing" her from a babysitter's house at just 6 months old.
And now, Stormie Clark is fighting back against the 24-year-old reality star's shocking allegations in an exclusive interview with Radar.
"I did not 'steal' Sophia from a babysitter at 6 months of age," Clarke insisted to Radar before explaining the incident.
"I saw Sophia for the first time at a park, with my oldest granddaughter, Ali, and my two daughters, Alissa and Kassy," she said, ending with a dig against Abraham's mother, Debra Danielsen, who was arrested for assaulting her daughter in a 2010 domestic dispute. "If I had stolen Sophia, there would be police records stating that, right? I have never been to jail, unlike Farrah's family."
She also argued that the coincidental park run-in occurred when Sophia was 15 months old, not 6 months.
Clark provided Radar with a photo of the emotional meeting.
"Nice try lying to make yourself look good in not letting Sophia see her own family!" Clark slammed. "There might be other people who lie down and claim to like and care about you, and tolerate your nasty attitude just to see Sophia, but I will never be one of them!"
As Radar previously reported, Abraham has arranged many reunions with Underwood's father, Jerry, his wife Debbie, and her children from a previous marriage. (Underwood tragically died at 18 in a car accident just two months before Sophia's birth.)
"Farrah is very loyal," Debbie told Radar about their relationship. "She wants Sophia to know our side of the family."
