Farrah Abraham is once again the subject of scrutiny after her co-star Mackenzie Douthit-McKee slammed her for making a sex tape.

According to Inquisitr, Mackenzie posted a retort via her Twitter page. As reported before, Abraham dissed the "Teen Mom 3" cast members by posting rude stuff about them.

In a previous interview with Abraham, she was asked what she thought about Mackenzie's alleged campaign for donations towards her breast augmentation operation, that also caused Mackenzie to be scrutinized before.

"You know what?," said Farrah, as reported on by the same site. "I didn't have to do that, but I definitely got - I got them for free, so I think if you have a big enough name you can do that, but if you don't have the money, don't do it. You need to work you're a** off and pay for it."

After Abraham released her statement, word got to Mackenzie quickly and caused her to fire back via her twitter account. "no wonder everyone loves @MaciBookoutMTV and not @F1abraham .... #justsaying," she tweeted.

Adding to this, she also tweeted another shade which fans are convinced is directed towards Farrah. This time, the "Teen Mom 3" star didn't tag or mention any names. Regardless, fans are sure that it was Farrah she was pertaining to. 

"Kudos to everyone who has never made a sex tape...," she tweeted.

The exchange has been considered by fans to be "entertaining" as to them, it provides great shock value.

As previously reported, Mackenzie went under fire for allegedly starting a campaign to fund her breast augmentation surgery. Her page indicated that she needed $5,000 to go through with the procedure. 

She quickly denied the claims and said that it is only her husband who will be able to see how her actual breasts look like.
