Earlier this week, Portwood appeared on a Teen Mom OG: Featured Moment, via MTV News, where she discussed her dream wedding to Baier, and revealed she'd like to have her co-stars, including Farrah Abraham, Catelynn Lowell and Maci Bookout, involved.

“My dream wedding, I know for sure, my cousin Krystal would be the maid of honor at the wedding because she’s the closest person to me. She’s like my best friend. And of course I want all the Teen Moms, all the girls, I want them to be my bridesmaids. I mean, they have to be a part of it.”
