The new season of Sister Wives could prove to be the most dramatic one yet for the Brown family.

Robyn Shares A Pregnancy Update

According to a press release from TLC, the Browns will be back this September for a new season, and the issues they face this time will be the most complicated yet, picking up directly after Kody and Meri chose to sign divorce papers dissolving their legal marriage. However, what was supposed to truly just be a shuffling around of paperwork, allowing Kody and Robyn to legally marry to make the process of adopting her children from her first marriage easier in theory, will prove to be a very different situation in reality.

In a preview clip for the season premiere, things seem to quickly go to an awkward place for Robyn and Meri when Kody's formerly legal wife tells the soon-to-be only legal Mrs. Brown about the divorce being official. However, the topic becomes a more painful one after Robyn asks Meri if she will attend the legal ceremony for her and Kody.

Are The Browns Faking Their Happiness For The Cameras?

"So have you given any thought to the idea of being there when Kody and I get a legal marriage?" she asks Meri in the clip.

Meri then goes to explain that she does feel differently than she used to -- and she thinks she can be there now, because she sees the whole situation as more of a team effort.

"I feel like I've dealt with it enough that I can see a bigger picture, and have that desire to be more evolved and more of a team player" she says.

However, even though things seem to be smoothed over quickly between the two women, according to the press release, they won't necessarily stay that way.

In addition to the change in the marriages, there will be problems which arise when Kody tries to spend a day at the beach with his daughters. In addition, the whole situation will likely change once again after Robyn announces her pregnancy.

Sister Wives season 6 premieres Sunday, Sept. 13 at 9 p.m. on TLC. A Best of Sister Wives Tell All will air immediately afterwards at 10 p.m.
