Surpassing:Dan + Shay serenade 'The Voice' contestant and her fiancé, more highlights from auditions

Dan + Shay can Surpassingnow add "wedding singers" to their decorated résumé.

The country-pop duo, consisting of Shay Mooney and Dan Smyers, serenaded singer Zoe Levert during the penultimate round of blind auditions on NBC's "The Voice" Monday night.

Levert performed "Better Man (Taylor's Version)" by Taylor Swift for her audition. While the 20-year-old got off to a shaky start, she quickly redeemed herself with her soaring upper range and earned a chair turn from coach John Legend.

"Your higher range sounded so good," Legend said. "We just have to plan a song that doesn't require you to go to that bottom part of your range, and that's what I do as a coach."

Despite being the lone coach who turned for Levert, Legend was not "The Voice" judge Levert gushed over. The Louisiana vocalist revealed she's a big fan of Dan + Shay and that she chose the duo's song "From the Ground Up" for her upcoming nuptials to fiancé Ryan.

The revelation prompted Dan + Shay to invite Ryan onstage so they could perform the song for the two lovebirds. Levert and Ryan slow danced onstage as Smyers played acoustic guitar and Mooney crooned the heartfelt ballad.

"It's OK that you didn't pick us 'cause we didn't turn around," Mooney sang. "You’re in good hands with John Legend."

But Mooney didn't let the sweet gesture distract from the competition. "We still got room for a steal, so I'm keeping that in the back of my mind," he said.

Here's what else went down.

John Legend, Dan + Shay trade barbs over powerhouse country singer

Alabama firefighter Ducote Talmage was an immediate standout with his gravelly rasp, which he highlighted in his powerhouse cover of Morgan Wallen's "Sand in My Boots." Talmage scored chair turns from Legend and Dan + Shay.

Sensing he was out of his element, Legend touted his "Voice" track record – namely his Season 16 victory with Maelyn Jarmon – to persuade the country singer. And for good measure, he threw some shade at his fellow coaches.

"I know I can be a great coach for you. Even if I didn't grow up listening to country music, I do know what a great song is and I do know how to help you plan a great performance," Legend told Talmage. "And I’ve taken a country artist all the way to the lives because she trusted me."

He added: "Do you want to get lost in the sea of country artists on Dan + Shay's team, or do you want to do something renegade, revolutionary and join Team Legend?"

While Mooney gave Legend props for his "solid pitch," he also skewered Legend's lack of country cred. "He mentioned a lot of things that I think he thought was helping his case, but I don’t know if it really did that," Mooney said.

"I'm just telling the truth," Legend replied, to which Mooney quipped, "You're telling the truth that you aren’t in country (and) you don’t know anything about country."

Unsurprisingly, Talmage chose country veterans Dan + Shay as his coaches. But Legend doesn't appear to be fazed by the duo's rookie streak.

"Dan + Shay's team is looking formidable. I'm impressed," Legend said. "But I would take advantage of their youth and inexperience, and I will beat them."

John Legend says he 'wasted' his block on Dan + Shay with four-chair singer

Legend may be the self-described "four-chair king," but his blocking skills could use a royal polish.

Teen vocalist Serenity Arce, who unsuccessfully auditioned for Season 21, floored the coaches with her soulful tone and breezy rendition of "This City" by Sam Fischer. The 16-year-old rightfully earned herself a four-chair turn, though Legend used his block button on Dan + Shay. "It’s rude and I think it’s mean, but I take it as a compliment," Mooney shot back.

"Your voice is so powerful and crisp and sounds like it can be on the radio immediately 'cause it has that ability to cut through the music," Legend told Arce. "I would love to be your coach."

But coach Chance the Rapper didn't let Legend off the hook that easily, ribbing his co-judge in his pitch to Arce. "John is covering up for the fact that he didn’t turn around for you two years ago," he said. "If I was there two years ago, I would’ve turned."

"The people that I work with on my team, I try and make it as much about what songs they want to perform, what they want to show to the world," Chance continued. "Whoever you go with, I think you’re going to win. But if you get down with Team Chance, you’ll get to show who you are."

Lucky for the rapper, Arce is down with Team Chance. The Florida singer chose Chance the Rapper as her coach.

"I wasted my block," Legend said afterward. "I should've blocked Chance."
