Farrah Abraham has reportedly been replaced on "Teen Mom OG" months after being fired for refusing to quit her career in adult entertainment. However, her replacement isn't who many fans thought it would be.

For months, rumors have been swirling in regard to "Teen Mom 3" star Mackenzie McKee being brought to the cast of "Teen Mom OG" as the series' fourth girl, but according to The Ashley's Reality Roundup, that isn't happening. Instead, Abraham will reportedly be replaced by another MTV star entirely.

On June 17, The Ashley revealed that Amber Portwood, Catelynn Lowell, and Maci Bookout will reportedly be joined by Cheyenne Floyd, who has previously been seen on MTV's "Are You The One?" and "The Challenge," and shares a four-year-old daughter, Ryer, with her "Challenge" co-star Cory Wharton.

In December of last year, after the child was seen on Floyd's Instagram page, Wharton was confirmed to be the father. That said, the couple was no longer dating at the time. Instead, they told their fans and followers that they had a co-parenting relationship with one another.

Despite her reported role on "Teen Mom OG," Cheyenne Floyd was never actually a teen mom. She was 24 years old when she gave birth to her daughter.

What happened with Mackenzie McKee?

According to The Ashley, MTV was in serious discussions about bringing Mackenzie McKee or Mackenzie Standifer, the wife of Ryan Edwards, to the show. However, both options reportedly “fizzled out” as the network came to the realization that fans weren't going to be all that thrilled with either possibility.

The Ashley noted that while McKee was "very interested" in joining "Teen Mom OG" as Farrah Abraham's replacement, MTV ultimately decided not to cast her. As for the "Teen Mom" special she reportedly filmed about her mother Angie Douthit's battle with cancer, that has yet to air and it is unknown if and when it will see the light of day.

Cheyenne Floyd and Cory Wharton will begin filming next week

Although MTV has not yet publicly addressed Floyd and Wharton's potential addition to the show, the report from The Ashley's Reality Roundup said that a production crew was heading to Los Angeles next week to start filming the former couple and their daughter. “It’s official,” a source said.

“The only way this doesn’t happen is if [Cheyenne Floyd] or [Cory Wharton] backs out, but contracts have likely already been signed so it’s highly unlikely.” “Their co-parenting relationship is nowhere near as happy as they try to make it out to be on social media,” the source added. “They will fit in perfectly."
