A tease that hinted Kody Brown was reversing all previous assertions that he was considering a fifth wife on Sister Wives has officially been proven to be just that-as the true identity of the next woman to move into a Brown family home has been revealed.

Meet The Newest Family Introducing Themselves To The Browns

According to a TV Guide synopsis for the Jan. 25 episode of the show, titled One More Woman in Kody's Life, the identity of the fifth woman is not a fifth wife for Kody-and is in fact, one of the moms.

"Christine's mom is moving in as her two oldest daughters prepare to set out on their own," the synopsis reads. "Meanwhile, Meri comforts Robyn, who continues to have problems with her ex-husband."

Are Kody and Robyn Hinting Future Problems?

Many have speculated that the fifth woman Kody previously teased was moving in would be someone's mom-and the synopsis has officially confirmed it.

Christine's mom may be moving in to help Kody's third wife handle the start of her having an emptier next these days, as her eldest daughters have both moved out because they're going to college. Aspyn and Mykelti are both gone, leaving the mom with her four youngest children-Paedon, Gwendlyn, Ysabel and Truely. Even though she isn't like Meri, who saw her only child, Mariah, move out as well, Christine could be having her mother move in to give her a hand raising the four younger kids-which she previously had help with when her eldest children were around.

Janelle has also seen her two eldest children-Logan and now Madison, also move out, but still has her son Hunter at home to help her with taking care of her three youngest-Garrison, Gabriel and Savanah.

Sister Wives airs Sundays at 9 p.m. on TLC.
