Farrah Abraham has just made her feelings towards Matt Baier's upcoming book crystal clear. However, she's done so in an indirect manner. As opposed to taking a stand against the fiance of her co-star, Amber Portwood, Abraham has shared a telling re-tweet about the publication.

In a message sent to Abraham's boyfriend, Simon Saran, a fan wrote, "That moment when they write a book and leave out their 50 kids and past and lies but write all about [Farrah and Simon]." Then, along with the message, with was re-tweeted by Abraham, the woman attached a Mariah Carey meme, which featured the singer asking, "Why are you so obsessed with me?"

Then, when Saran appeared to be ready to apologize for making the statement during the "Teen Mom OG" reunion last year, Abraham interjected and said that Baier does resemble a pedophile. Right away, Baier and Portwood reacted badly to the comment and a massive on-set fight between the group, and Abraham's father, ensued.
