Farrah Abraham is at it again. The “Teen Mom OG” star is being accused of exhibiting diva behavior while filming new episodes of the MTV docuseries.

Despite having four bathrooms inside her Austin, Texas, home, the Ashley’s Reality Roundup reports that Farrah, 24, refuses to let the MTV crew use them. While filming her segments of the reality series, which also stars Maci Bookout, Amber Portwood and Catelynn Lowell, sources say she requires them to use rented portable toilets.

“She flat-out refuses to let any of the crew use her bathrooms, even the producers who have been with her since the '16 and Pregnant’ days,” a source said.

While the Ashley reports that the “Teen Mom OG” crew includes roughly 10 people, the other girls have no issues accommodating the show’s workers. “We always ask before we use [their bathroom],” one source said. “We try not to intrude.”

If the rumors are true, this isn’t the first time Farrah has exhibited questionable behavior while filming “Teen Mom OG.” Viewers will remember that MTV axed her from the series reboot in 2014, only to bring her back as a starring cast member a few weeks into filming. In her first scene of the new season, Farrah cried and stormed off after disagreeing with producers over her story line.

In the scene from "Teen Mom OG," posted below, one of the show’s producers, Heather Walsh, warns co-producer Larry Musnik that Farrah may be “annoyed” when they go into her home. “I’m not throwing you under the bus,” Heather says. “But I’ve been yelled at.”

Larry responds saying he doesn’t think Farrah will yell at him. Heather disagree, saying she thinks the "Teen Mom OG" star will "shut down production."

When Larry sits down with Farrah inside her home, they discuss giving her a proper introduction. “How does one day your fans all of a sudden see you when they tune in to the show? How does that start?” Larry asks after Farrah says she wants her first scene to "be real."

“Whatever. We all agree on the same thing; it’s weird that I wasn’t a part of it. Now I’m a part of it. The end,” Farrah says before walking out of the room in tears. “You guys just like make me more f---ing mad."

At the tail end of the season in May, Musnik spoke out about his relationship with Farrah. When asked by Cosmpolitan if he felt he was tough on the reality star, Musnik said it was “important” for him to be. “Farrah sometimes needs that. I think she needs someone to be that voice,” he said. “She tests everybody around her. Her family, everyone in her life will get a little bit of that. I can be the one that’s a little harder [on her]. I think she ultimately respects me for it.”

“Teen Mom OG," a reboot of MTV’s popular “Teen Mom” franchise, premiered in March. “Teen Mom OG” was reportedly renewed in July. MTV has not announced a premiere date.
