"Sister Wives" Season 7 is expected to return on air this 2016 but no definite date has been announced. So, as we wait for more updates about TLC's controversial series, Robyn Brown, one of the wives in Kody's polygamous family has recently tweeted about her excitement on welcoming her new baby just two days before her due date.

The Brown family from TLC's "Sister Wives" is hugely different from any typical American family. While they go through the same as any other household, having four wives, one husband and 17 children is extremely far from the norm. And this 2016, the clan is getting bigger as Kody and Robyn Brown are set to welcome their second child on Jan. 7. The couple's new daughter will be Kody's 18th child.

"Two days away from my due date," Robyn wrote on Twitter. "We are all ready to meet Baby Sister! Trying to be patient but can't wait to see her sweet face."

Robyn's pregnancy is expected to be part of "Sister Wives" Season 7 as well as her three children, who were one of the main reasons Kody divorced her sister, Meri, after being his legal wife for more than two decades. After the divorce, Kody legally married Robyn. And despite their awkward situation, Bustle previously reported that everyone in the family, from the three other wives to the older children, are all excited for the arrival of the newest member of the Browns.

Aside from the arrival of Robyn's daughter, the Browns will also face new challenges as more drama is expected to ensue between Kody and his other wives, Meri, Janelle and Christine, who were rumored to be on the verge of leaving him, as previously reported. And according to Vine Report, the wives' imminent departure has been because of Kody's bullying ways. Since he is also spending most of his time with his new wife, his other wives felt neglected.

There is still no confirmation from TLC regarding the reports and rumors on the other wives' departure but recent updates suggested that the narrative of the upcoming season of "Sister Wives" will most likely follow that direction. It was also reported that the show will focus more Kody and Robyn's relationship as a married couple. So, what will happen to the other three spiritual wives?

Due to Kody's selfishness and bully attitude, the tension in "Sister Wives" Season 7 is becoming more palpable than ever. An insider even said that the Browns do not exactly have "the loving polygamist marriage" the viewers often see on television.

Meanwhile, watch the Browns as they deal with the aftermaths of Kody's new marriage as well as Robyn's pregnancy in "Sister Wives" Season 7 this 2016. For free online stream link, click here.
