Not backing down. Teen Mom OG’s Amber Portwood clapped back after costar Farrah Abraham called her a “knockoff” Miss Piggy in an insensitive Tuesday, November 29, social media post.

Abraham, 25, took to Instagram Tuesday night to share a meme featuring a picture of Portwood, 26, next to an image of the iconic and curvaceous Muppets character. The meme read, “I’m not Farrah … Definitely not. Ur Miss Piggy!”

“Lmao I love fans they make the best s--t you can't say out loud 😹😹😹😹👑👑👑💯💯💯💯💯💯,” Abraham captioned the 'gram. “By the way Iove miss piggy but not the knock off.”

Portwood fired off a heated response to Abraham in a comment on the post. “Miss Piggy looks classy with her pearls..I like this..hey so how are you and that guy from NY doing?” she ominously wrote.

“And sorry I didn’t do that show with you and it didn’t get picked up,” Portwood continued, referring to a mysterious TV project. “Have a good night Hun..if you want to keep going then I have plenty to share?? Just let me know.”

As viewers saw on the Monday, November 28, special that aired after the season finale of TMOG, Portwood went in on Abraham when pressed by Dr. Drew Pinsky about the status of their friendship.

“We used to be [friends] and then she decided to open up her crooked lips. She decided to do an interview saying something about how it's good that [my daughter] Leah is with Gary [Shirley] and how my house probably smells like piss. You don't do that," Portwood fumed. "She's been mean to Catelynn [Lowell], Maci [Bookout], my fiancé [Matt Baier], Taylor [McKinney], everybody on this show and her piece of s--t boy toy Simon [Saran]."

The Never Too Late author then took a dig at Abraham’s 2013 sex tape and her subsequent career in the adult entertainment industry. "When she makes a quote saying she's the reason why this show is on, well, I'm sorry, when I went to prison, this show was not on and when I got out it sure as hell was on," she continued. "And she was selling her vagina while I was gone. We'll make that clear."

In a preview for part two of the reunion special, Portwood storms on stage and launches into a verbal tirade against the Farrah Superstar: Backdoor Teen Mom star after Abraham suggests that Portwood’s 46-year-old fiancé, Baier, looks like “a pedophile.”

Part two of the Teen Mom OG finale special airs on MTV Monday, December 5, at 9 p.m. ET.
