Sister Wives season 19 star Meri Brown recently addressed her "tension" with Robyn Brown, and it sounds like the two women are no longer close. Meri, 53, was the first wife of polygamist patriarch Kody Brown's first wife. The couple married in 1990 and had one child together. Robyn, 45, was Kody's fourth wife. They married in 2010, and had five children together, including three from Robyn's previous marriage.
