'She's Fat, Lazy, & Can't Move!' Farrah's Mother Debra Can't Keep Her HARSH Opinion A Secret

Does a mother know best?

In a sneak peek clip for Teen Mom OG, Farrah Abraham, her daughter Sophia, her mother Debra and her fiancé, David, sat down for a dinner together. "Your mother has been very, very happy that you guys are talking, that's really good," David told the 25-year-old. She replied, "Yeah I appreciate it."

As seen on previous episodes, Farrah got a new nanny for her 8-year-old daughter. She bragged about how well she has been working for her, but Deb doesn't agree! "She's fat, lazy, and can't move," Deb blasted the nanny. David replied, "That's not very Christian." Ouch!

Do you think Deb's comments were too harsh? Teen Mom OG airs Monday nights at 9pm ET, only on MTV!
