In the podcast's latest episode, Unglert revealed that he got a "new" placeholder engagement ring for Miller-Keyes after mistakenly losing the original one, which was a 4.5-carat emerald-cut diamond.

"It might be in the garage somewhere but yeah, moral of the story is don't put your engagement rings in the junk drawer," he said. "So I did have to go out and buy a placeholder ring for now, but it's not quite as nice as the first one was."

"It'll happen by the time this podcast airs," Unglert said. "Maybe. Maybe the day after it airs."

Miller-Keyes also spoke to PEOPLE in September about their engagement, noting that she had "no clue" as to when Unglert would propose. She did, however, have an idea about what she wanted for their eventual nuptials.

"I think we just want to elope," she revealed. "We recently went to his brother's wedding where they engaged and then married the next day. It was solely about their love, so we just want to focus on our love, and it just be about that and nothing like … extraordinary."

Miller-Keyes also shared how they were "getting very, very close to choosing a date" and envisioned a wedding for sometime next year.

"I want to [begin planning] so badly, but I keep hearing from my friends who are married, they're like, 'Just take every moment as it comes. Don't rush anything. Enjoy where you're at,'" she said. "So I'm like, 'Just hold your horses. You're not even engaged yet.'"
