People Editorial Guidelines Published on February 15, 2019 12:00PM EST Another Sister Wives star is off the market! Mariah Brown popped the question to girlfriend Audrey Kriss at the Women’s March in Washington, D.C., on Jan. 16. “We had just started dating when we came for the first time two years ago and it was such a special time for us that I wanted to propose there,” Brown, 23, tells PEOPLE exclusively. The couple has been together for just over two years and first met while attending Westminster College. “I had a huge crush on Audrey for a little over a year before we started dating,” Brown says. As for the moment she knew Kriss was the one? “I can’t exactly pinpoint, but it was pretty early on. There are a lot of things about Audge that I am so in love with and I knew that I wanted to love those things for the rest of my life. She made me a better person and continues to make me a better person.” Claire Bruce/TLC Brown, who is the only daughter of Kody and Meri Brown, said she wanted the engagement to come naturally. “We were in the middle of where everyone was marching and I was trying to get the ring out of my pocket, where it was stuck. I think Audrey was fixing her hair, but I just got down on one knee and said some sweet things that neither of us can really remember because we were so caught up in the moment,” she says. Claire Bruce/TLC “She was really sweet and started crying and I was crying and then I put the ring on her, got up and gave her a kiss and someone around us goes ‘Did she say yes?”’And she totally hadn’t yet! Then she said ‘I do! I do!’ and then realized that was the wrong thing to say and then said ‘Yes!’ She’s such a sweetheart. The ring is absolutely perfect, if I do say so myself.” Claire Bruce/TLC The couple is taking their time when it comes to wedding plans, but say their loved ones can’t wait for the big day. “Our friends and family have all been so excited for us! I actually think my dad almost cried! He really likes Audrey. All of our friends have been so sweet and offering to help and our families are obviously excited to share their input.” Sister Wives airs Sundays at 8 p.m. ET on TLC.
