The 24-year-old, who first appeared on 16 and Pregnant in 2009 – fought with producers on Monday's finale, refusing to film because she says they denied her request to star on another reality show "about struggles with my mother" – which they called a breach of contract.
"You know what's so f---ing laughable right now?" she told producer Larry Musnik. "I'm laughing, I would love to not laugh in your face, why are you so white trash?
It only got worse from there.
"What a dumb, twisted motherf------!" she said.
"This entire thing for you is because of this show!" he yelled back. "We walked in the door when you were in a cheerleading outfit. This gave you your start."
"Sophia's dad died, that's what got your s--- picked up," Abraham screamed, crying.
Flashback: It’s a Teen Mom Reunion
(Abraham's original storyline revolved around her coping with becoming a single parent after the father of her now 7-year-old daughter, her high school boyfriend Derek Underwood, died in a car accident when she was eight months pregnant.)
"Son of a bitch, get the f--- away from me," she shrieked, pushing Musnik.
"It is not that!" he insisted. "We stood by you every step of the way!"
"Go f-- yourself, and I will never work with you guys again," she yelled before running into her home.
Abraham tweeted a clip from the altercation Monday, writing "Don't Mess with this mama's family."
Still, previews of the reunion special show Abraham – who's been a controversial figure on the show because of her porn career and feuds with the other moms – participating.
Part 1 of the Teen Mom OG reunion airs Monday at 10 p.m. ET on MTV.
