Sister Wives' are adding another wife to their growing family, share stunning engagement news

The "Sister Wives" show has added a new member after 23-year-old Mariah Lian proposed to her longtime girlfriend, Audrey Kriss.

The popular Brown family of TLC’s "Sister Wives" is adding another wife to their ever growing family. The 18-member family is rather famous for their star reality series which captures their unconventional polygamous life. They have constantly blossomed adding on new members as the kids continue to grow and have kids of their own.

Mariah Lian, who is born to Kody and Meri Brown, recently popped the big question to her girlfriend of two years. Mariah came out as gay to her parents in 2017, and though initially shocked, they have since shown great support of her.

Overjoyed, they chose to announce news of the engagement through TLC who proudly shared a photo of the lovely duo and captioned it with the words:

“A picture worth 1,000 words! #SisterWives Mariah is engaged to girlfriend Audrey. Visit TLCme.com to hear all the details!”

PEOPLE reports that the young couple first met while attending Westminster College. Mariah told sources of how she'd had a crush on Kriss for about a year before they actually started dating.

She proposed in January during the Women’s March, just a little after they had celebrated their dating anniversary. All lovey-dovey, she explained that the event meant a lot to them as they had made it a tradition of sorts since they started their relationship.

A very excited Mariah also gushed about Audrey’s reaction to the surprise proposal saying:

“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…Audrey 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 goes ‘I do! I do!’ and then realized that was the wrong thing to say and then said ‘Yes!'”

How sweet!

The Browns, despite the disapproval of many, have continued to soar. As proud polygamists that are members of the "Apostolic United Brethren," they have constantly faced objections.

The most memorable is perhaps when they had to leave their Utah home after being faced with possibilities of getting detained for practicing polygamy.
