Caleb kept it traditional by asking her Maddie's father, Kody, for approval, according to People. He then took his fiancée-to-be to a look-out point, where he surprised her with a blue diamond ring. 

"It was cold and we were huddled in jackets and I thought he was crazy to stop," Maddie told the magazine. "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. I started kissing him and saying, 'Yes, yes!'"

After the announcement, Maddie's family and friends shared an outpour of congratulations on Twitter.
"My best friend is engaged!!!!" wrote Dezi Mascarenas. "Congratulations @MaddieR_Brown and Caleb!! I'm so happy for the two of you!!!"

Maddie’s sister, Mykelti, gushed, "My wonderful sister @MaddieR_Brown is engaged!!! And to an increadible man."

Even Kody's third wife, Christine, got in on the excitement. "Seriously?! They're perfect together. Congratulations @MaddieR_Brown and Caleb," she tweeted.

Although Maddie is known for being on the TLC reality show about her polygamist parents, Kody and Janelle, she and Caleb have decided to be live a monogamous lifestyle.

"We are not living a plural marriage," Caleb tells People. "We support Maddie's family with their choice of living plural marriage, and they support us with our choice in just marrying each other."
