She said yes! Sister Wives star Aspyn Brown is officially engaged to her longtime boyfriend Mitch Thompson. The couple shared the exciting news with fans — and revealed he popped the question while on vacation in Seattle.

"Mitch and I are engaged," Aspyn said in a video posted on the TLC website. The newly engaged beauty also showed off her engagement ring, which features a round-cut diamond on a gold band. "We've been dating for a long time, so I just kind of knew that marriage was the next step," Mitch sweetly added.

Aspyn continued, "When Mitch asked me to marry him, I was super excited… very happy. I was expecting it a little bit, but it was all perfect." The couple went on to share how they can't wait for the wedding and have plans to move in together.

The 22-year-old beauty is the daughter of Kody Brown and his third wife Christine, and while Mitch is a longtime friend of the family and involved in the family's Apostolic United Brethren religion, it appears the couple has no plans to live a polygamist lifestyle. "I don't want to do plural marriage," she said in 2015. "I kind of feel bad that none of us want to, but it was just not what we were meant to do I guess."

Her sister Mykelti Brown, who tied the knot in 2016, also revealed she would not be following in her parents' footsteps. "I'm not going to live polygamy. I don't think that's for me," Mykelti explained. "I don't think I could ever live up to what my parents have been able to do." It appears Aspyn might not be the only family member tying the knot this year. Her older brother Logan, whose mom is Kody's wife Janelle, also recently announced his engagement to girlfriend Michelle Petty, writing, "I did a thing… the best thing I have ever done. #engaged." Congrats to the happy couple!
