Maci Bookout is unimpressed with Farrah Abraham.

'Teen Mom OG' Stars Attend The 2015 MTV Movie Awards

Following Abraham's surprise return to Teen Mom OG earlier this year, Bookout has continued to express her frustrations in her co-star's career, and in a new interview, she took aim at the way Abraham treats others.

“One thing I don't understand is the way she talks to people,” Bookout noted during an interview on the Teen Mom OG: After Show, via a report by Wetpaint Entertainment on Tuesday. “You just don't treat people that way no matter how you're feeling. If she feels a certain way, there's a way to get that across without being so ugly. You don’t have to be so mean.”

When Bookout signed on to return to the series for Teen Mom OG, she was unaware that her co-star, Abraham, would soon return, as well. In fact, none of the women were aware of what was in store for the show until filming had begun.

Although Bookout has claimed in the past that she doesn't have a personal problem with Abraham, this latest interview appears to hint at otherwise, and is sure to cause a stir among her co-stars.

In addition to Bookout's feelings on Abraham's behavior, she also does not want her 6-year-old son, Bentley, tied to a show, which features someone who starred in a sex tape.
