'Sister Wives' season 7 spoilers news: Maddie Brown weds, doesn't want a polygamous marriage

Maddie Brown, the 20-year-old daughter of "Sister Wives" patriarch Kody Brown, has married her fiancé Caleb Brush.

Maddie is Kody's daughter with Janelle, one of his four wives. She appears, along with the rest of her large extended family, on the TLC reality series.

"Sister Wives" follows the lives of Kody and his wives Meri, Janelle, Christine, and Robyn, along with their 18 children.

On Saturday, June 4, Maddie married Caleb in what Us Weekly described as an "intimate outdoor ceremony" in Montana. Her entire family was there to celebrate her special day, with her father officiating the wedding.

According to the outlet, the bride wore a classic strapless white gown accentuated with a string of pearls, while the groom wore a white shirt with a grey waistcoat and khaki pants.

The couple have previously made clear that while they respect Maddie's family's set-up, they prefer to have a monogamous relationship.

"We support Maddie's family with their choice of living plural marriage and they support us with our choice in just marrying each other," Caleb told People magazine in September.

According to Us, Maddie and some of her siblings have previously spoken out about not wanting to have multiple wives/husbands when it comes time for them to marry. In a TLC Tell-All special in November, Maddie said, "I'm not one to live plural marriage."

Maddie and Caleb were engaged in September. Caleb proposed to his now-wife while the two were enjoying an ATV ride at a scenic spot.

"It was cold and we were huddled in jackets and I thought he was crazy to stop," Maddie told People. "He said to come look over here. So I walked with him to the edge. He told me he could never express how much he loved me, but he wanted to spend his life trying, and went down in one knee and pulled out a box."

Apart from Maddie, advertising salesman Kody has five other children (Logan, Hunter, Garrison, Gabriel, and Savanah) with Janelle.

He has 12 other children with his other wives.

"Sister Wives" airs Sundays at 8 p.m. ET on TLC.
