On the upcoming season premiere of MTV's "Teen Mom OG," Farrah Abraham gets into a heated argument with her mother Debra over laundry soap. The reality star treats her mother harshly, bringing Debra to tears and Farrah's 6-year-old daughter Sophia even steps in to scold her mom.

In the sneak peek, Farrah is discussing the house rules that she's laid out for Debra, who is in charge of taking care of little Sophia while Farrah is away on a work-related trip to Europe. One of Farrah's rules is Debra is not allowed to run the washing machine for only two items of clothing because it wastes laundry soap and Debra offers to buy her own soap.

"Oh, I'm not worried about the soap and if that's a b--chy comment, you should probably hold it back," the 24-year-old tells her mother. "Don't come at me like that."

Debra tries to diffuse the situation and tells Farrah she wants nothing but the best for her on her upcoming trip and Farrah interrupts.

"You know what I want, I want my mom to understand me and I want her to not be a b---- to me when I say how I like things done," she tells her mom.

They continue to argue and Farrah dominates the conversation until her daughter Sophia comes over and starts hitting her mom on her arm, slapping her multiple times.

"You are having a bad attitude," Sophia tells her mom, scolding Farrah with her hands on her hips.

"I don't have a bad attitude, I care and I love you and I'm making sure that you're taken care of," Farrah explains to Sophia, then continues to speak harshly to Debra.

"You don't need to be mean to me," Debra says, crying.
