Sister Wives season 6 will premiere in fall this year and it is being speculated that Meri Brown may quit the show after Kody Brown and Robyn's legal wedding, which may take place during the upcoming season of TLC's family reality show.

Since the 44-year-old maintained silence during the couple's 25th wedding anniversary, the rumours were further fuelled that she may leave the Brown home.

The otherwise active mother of teenager Mariah, stayed away from her official social media accounts even as her family sent congratulatory messages. On Twitter, she has been posting messages about "believing in signs", "achieving her dreams" and about her "getting back to further education".

Moreover, Meri has been noticed maintaining some distance from her former husband and other sister wives and was not retweeted any of their posts since sometime now.

Sister Wives season 5 ended on a shocking note, when Meri declared that she would divorce her husband Kody to make way for Robyn to become a legal wife of the polygamist.

The reality television star ended her 24-year marriage with the Brown patriarch -- who has three more wives (via spiritual weddings) -- last year. Her step was claimed to be a noble sacrifice as Robyn's children from her previous marriage, would now get legal benefits from their stepfather.

Season 6 of the family reality show is expected to focus on the 45-year-old polygamist and Robyn's wedding as this will allow Brown to legally adopt his fourth wife's children from her previous marriage.

TLC is yet to announce the premiere date of the next season of its popular, but controversial, reality show Sister Wives.
