Sister Wives season 18 cast

Sister Wives is the story of a plural family comprised of Kody Brown, his first wife Meri, his second wife Janelle, his third wife Christine, his fourth wife Robyn and their combined 18 children. 

Over the years, Sister Wives explored the family's move to Las Vegas as they fled the laws against polygamy in their original Utah home. From Las Vegas, the family moved to Flagstaff, Ariz., to build their dream compound, but trouble started brewing in the marriages as COVID-19 struck and the pandemic changed how the family interacted. 

While the older kids started going to college, moving away, getting married and having babies, Kody's relationships with his wives started deteriorating. Christine was the first wife to leave him in November 2021. Janelle followed in December 2022, followed by Meri in January 2023, leaving Kody and Robyn as the sole couple remaining.
