Maci, a good girl, had some serious objections to appearing on a show with Farrah, even though she didn’t have to interact with her, because Farrah Abraham had released pornographic videos of herself. Maci threatened to leave the show if Farrah remained. But eventually Maci agreed to keep filming. Allegedly, Maci cheered on Amber as she went out to confront during the show taping recently.

Kailyn and Javi have gotten into it a few times on and off camera. One day, when Kailyn’s friend brought her young child over and Javi refused to put the dogs outside or in another room, Kailyn became furious at him for his lack of help. She ran upstairs to him claiming she was going to “knock him out” and ended up pushing him backwards.
Farrah vs. The Producers
We all know how much Farrah hates the show’s producers now, even though they help facilitate her getting money. And she constantly clashes with them despite being in breach of contract, especially Larry. One of her epic fights with them has become famous.
