Sister Wives season 6 premiere date revealed: Robyn's pregnancy to bring major drama in the Brown family

Sister Wives season 6 will premiere in September and according to some special footage released by TLC and The Wrap, the upcoming American reality series will feature some major drama.

Season 6 will commence from the divorce saga between Kody Brown and his wife of 25 years Meri.

In the footage, the 44-year-old reality TV star can be seen discussing her separation from the Brown matriarch with Robyn, and it seems like an awkward situation.

Robyn feels that Meri should have spoken to Kody instead of her about the divorce.

Then, Meri looks at the camera and says that she is depressed about the entire situation, but when she thinks about the future of Robyn's children, she feels happy about her decision to allow the 36-year-old to become the legal wife of the polygamist.

Moreover, in the upcoming season, the Brown family will deal with a lot of changes post the divorce and Kody's subsequent marriage to Robyn.

The couple had already declared that Robyn was pregnant with her fourth baby and the official Facebook page of Sister Wives is celebrating the news by regularly updating fans of the baby's growth.

According to The Wrap, "The Browns begin their journey to legally adopt Robyn's children from a previous marriage. Kody also takes his youngest daughters to the beach in an attempt to bond more with them, and Robyn announces her pregnancy to the family, kicking off the countdown to her due date."

However, rumours now suggest that the relationship between Meri and Robyn have gone sour, post the divorce. Meri, has reportedly distanced herself from sharing any news about the Brown family. She even remained silent around her 25th wedding anniversary.

After Robyn's baby news, Kody's second and third wives Janelle and Christine congratulated the couple, but Meri maintained silence sparking rumours that she may have moved out of the family.

Sister Wives season 6 premieres on TLC on 13 September at 9pm ET/PT. This will be followed by the "Best of Sister Wives Tell All" special.
