"Sister Wives" Season 7 is definitely getting more dramatic as the upcoming season will concentrate more on Robyn's children and her relationship with Kody. Meanwhile, the other ladies including Meri, Janelle and Christine will take the backseat.

While the previous season of the controversial TLC series has been successful, some fans are quite skeptical about the latest change of focus. Also, with Robyn's pregnancy of Kody's 18th biological child, they can expect to see the dwindling relationships of other sister wives.

As "Sister Wives" Season 7 is set to air early next year on TLC, here are four latest scoops about the upcoming season of the polygamy-themed series.

1. Meri, Janelle and Christine will finally leave polygamous hubby Kody in "Sister Wives" Season 7?

Aside from focusing on Robyn and Kody's relationship, Design & Trend noted that the upcoming season of the hit TLC series will show Meri, Janelle and Christine leaving Kody because he has been bullying the sister wives for years.

"It's just not the loving polygamist marriage people see on TV... This family has been torn apart," an insider told RadarOnline.

2. Kody only wants to spend with his new wife and three adopted kids.

There were also rumors that "Sister Wives" Season 7 will concentrate more on the lives of Robyn and Cody as a newlywed couple. Their union came after Kody's longtime wife Meri agreed to divorce him for the sake of Robyn's three kids from her previous relationship. Since then, Kody only wants to spend time with his new wife and three adopted children.

"He really only wants to hang with Robyn," a source said. "There's a ton of tension. He's a total bully. It's miserable behind closed doors."

3. Robyn knew about Meri's catfish scandal?

As the family deals with the aftereffects of Meri's catfish scandal, an insider close to the family revealed that her sister Robyn knew about the incidents but never told her that she was being fooled, Fashion & Style reported.

"Robyn absolutely knew from the beginning that Meri was being catfished," a source explained to In Touch. "Robyn sat back and just watched as the whole scam unraveled."

4. "Sister Wives" Season 7 will also focus on the custody battle between Robyn and her ex-husband.

Apart from the impending birth of Robyn and Kody's daughter in early 2016, the upcoming season will also focus on the past custody battle between the Browns and Robyn's ex-husband, another Fashion & Style revealed.

Meanwhile, "Sister Wives" Season 7 will premiere on TLC sometime in 2016. For free online stream link, click here.
