The couple received congratulations from their Ultimatum family, with host Vanessa Lachey writing, "Wow! Congratulations Mama. ❤️❤️❤️❤️"

Riah's trial marriage partner, James Morris, commented, "Congratulations!!! Another Ultimatum baby 😍."

James' fiancée Ryann McCracken also commented, writing, "AWH🥹🫶🏼 congratulations you guys, I’m so happy for you!"

Trey and Riah had been together for two years when he issued the ultimatum. Riah was hesitant to take the next step in their relationship because she had never witnessed a "happy, healthy marriage" before.

The final episode saw Trey propose to Riah, and her surprisingly saying yes. At the reunion, the two confirmed they are still engaged and currently planning a destination wedding for spring 2025.

"I want a gold wedding, I want it to be perfect," Riah said, as Trey added, "Things are good, but I think work, our work schedules, real life hit us again so we're still working through that as far as getting on the same page and whatnot. But overall our relationship, it's like night and day from what it was."
