Farrah Abraham is out and Mackenzie McKee is in officially, according to TMZ reports. MTV has made the final decision! The celebrity news site reports that sources close to production on MTV's "Teen Mom OG" reality series have revealed Mackenzie McKee, who is also a fan favorite mom has already begun shooting scenes.

Out with the rude and in with the new

As previously reported, McKee was in line to fill the "Teen Mom" void created after Farrah Abraham was fired, or Jenelle Evans potential vacant spot should producers decide to nix her from the series also.

Farrah set her feet and took on MTV when she was given the choice to stop with the adult entertainment or stop with "Teen Mom," and she chose to keep her lucrative adult entertainment gig, so bye bye reality television!

Will Jenelle Evans be the next to go?

Many fans were glad for the most part to hear that Farrah was out. She is not a likable member of the cast and even the other moms have a difficult time dealing with her mightier than thou attitude.

Fans are very excited to see Mackenzie joining the show. The network has already shot a two-hour special with McKee about her mom's battle with stage 4 brain cancer. Mackenzie is no rookie in reality television. She was was part of the 'TM3' franchise before getting canceled after one season in 2013 and will a breath of fresh air after Farrah's dramatic exit.

Fans are not only happy Abraham is gone, but also hope she will one day get her parenting act together. Abraham was recently slammed across social media after revealing that she had nude photos of her daughter Sophia on her phone, and Sophia had hers also stating it was no big deal.

Fans did not agree with that any more than they have agreed with Jenelle Evans gun photos of herself, David Eason and Jenelle's 3-year-old son Kaiser following the Florida school shootings.Social media followers bashed the couple for the photos calling them inappropriate and insensitive.

David Eason has already been fired from MTV and "Teen Mom" for his inappropriate homophobic rants on the social media. Jenelle's fate still appears to hang in the balance. However, it is not looking too good for her at this time. She seems to be standing by her man, despite the cost. That cost could be her job at MTV.

Looks like MTV is through catering to some of the diva cast members and the word is out the show will go on, one way or another.Kudos to the network on their zero tolerance policy. Way to stand your ground! What are your thoughts on the "Teen Mom OG" cast shake-up, are you glad Mackenzie McKee is a go? What do you think will happen with Jenelle Evans?
