Adkins, known for country singles like "Honky Tonk Badonkadonk" and "You're Gonna Miss This," appeared to sing a few bars with Shelton and talk with his team members.
Shelton cracked jokes with him, but Adkins was more of the straight-man while Shelton quipped.
"I like that attitude already," Shelton told one contestant.
Adkins replied, "I'm looking forward to it."
Shelton gave him a quizzical look and Adkins said the phrase again, appearing a bit irritated.
"I know, even though you didn't say it very loud," Shelton said. "I couldn't understand what you were saying. ... I just want to see what time your good mood starts and wait 'til then to start talking to you."
Fans loved the back and forth between the pair and took to Twitter to share their admiration for Adkins.
"Just when you thought The Voice couldn't get any better, Trace Adkins shows up as a mentor," viewer Jeanette Ustaszewski wrote.
Fan Erin LaRocque added, "Watching Blake Shelton and Trace Adkins coach two singers through an Ariana Grande song is exactly what I needed in my life."
