'Sister Wives' season 6 update: Who's moving out and moving in?

As if the Brown household hasn't become chaotic enough, rumor has it that another wife might be making her way into the family. Is it possible? Is Kody marrying his fifth wife? 

Despite the very unusual and controversial set up of the Brown Family in "Sister Wives," it has managed to continue running for six seasons now. There's no sign that the show is slowing down, seeing how interesting the new season will be. A new addition to the huge household can create a whole new story that will turn things around. 

Kody Brown is the head of the household. The 44-year-old salesman is already married to four wives and has 17 kids in total, all of which are living in the same home. With rumors pointing to a new woman in the house, Kody addresses the issue of him marrying again. 

In the previous episode, Kody tackled it head-on, saying. "I really don't think so, that's not in my stars ... I talked earlier about how it is to have all my wives sort of say, 'Hey I miss you, I feel like I'm getting cheated on time.' We are good then, if nobody is really feeling like we have this huge abundance of time, I think we have met our capacity and we are going to stay with it the way it is."

Meanwhile, Ecumenical News reported that this rumor may have started due to another rumor saying that Meri will be leaving the house as she is the only one without a child. Christian Today added that Meri feels like she "doesn't fit in" and is not happy with the situation already. 

So, if Meri is leaving and Kody isn't marrying a new wife to replace her, who is the new woman moving in then? Christian Today speculates that it could be Kody's mother. She may be visiting to help around the house as well as spend time with her four daughters-in-law and 17 grandkids. And since Kody's father died back in 2013, Kody's mom may want some company for a change. 

"Sister Wives" will return with a new episode on Jan. 11.
