Brown, 19, is engaged to Caleb Brush, 28, a mining equipment repairman.
Brush asked Kody for permission to marry his daughter, which he granted, and sister wives Meri, Robyn and Christine tweeted their support for the couple.
After completing her first year at Utah State University, where she was a member of Kappa Delta, Brown moved to Montana to live with Brush. When asked on Instagram if she would be returning to USU, she replied she would not be coming back this year.
We don't know when Brown and Brush met, but in retrospect, her joyful tweet on July 11 is most likely about their relationship.

Brush proposed to Brown during an ATV outing, and she told People they're planning an outdoor wedding. The couple also had some furry guests at their engagement photo shoot.
In 2012, Maddie spoke about her desire to live differently from her parents, declaring that a polygamous marriage wouldn't make her happy. Brush, in an interview with People, affirmed that the couple would be marrying just each other, but that they remain supportive of the Browns' lifestyle.
