During a recent appearance onMike JohnsonandBryan Abasolo’sTalking It Outpodcast,Adams' dad Desmonddescribed his future son-in-law as “humble,” “genuine” and an all-around “good guy.”

“What you see is what you get,” Desmond said. “And that’s what I really liked. A lot of people, as you guys know, they used [being on the show] for whatever [they were] promoting. I think it was pretty new to Zac, if I recall, as well. He wasn’t really a follower [of the show] for so many years or whatnot.”

“During our [first] conversation, we had some good heart-to-hearts, even on our first talks,” he added. “I was happy with him, I was really happy with him. [I’m] so happy with just how things are progressing. It’s nice. He’s a great guy.”
