Blake Shelton will return to his coaching position on Season 20 of NBC's The Voice, and he's got some major talent lined up to assist him. The country star enlisted Grammy-winning duo, Dan + Shay to serve as his team's advisors for the show's battle rounds.

"The battle rounds are literally, you know, two artists coming together and making music, singing basically a duet. We call it a battle but it’s a duet. And these two are obviously, I have to talk about their career, it’s completely exploded," Shelton said during an appearance on Access alongside Dan Smyers and Shay Mooney.

"But the way they come together and vocalize together and make music, I thought that would be a great mentor to have these two because so many times, I’m sitting here in a situation in these battle rehearsals and one of the artists will ask me a question about harmony and I don’t know crap about harmony," he continued. "I would be like, ‘Oh yeah I will check on that for you’ and I never do because I don’t know anything about harmony. Finally, this season, I’ve got Dan + Shay here and they kill it and they’re natural at it and honestly, it’s already come into play a couple of times and it’s helpful to have them here."

Dan + Shay released their debut single, "19 You + Me" in 2013, which was followed by their first studio album, Where It All Began in 2014 and Obsessed in 2016. The duo's career really took off thanks to their crossover smash, "Tequila," which was followed by another hit, "Speechless." Both songs earned them a Grammy for Best Country Duo/ Group Performance in 2018 and 2019. Additionally, Dan + Shay's 2019 collaboration with Justin Bieber, "10,000 Hours," has also been a major success for them.

Dan + Shay's upcoming appearance on The Voice will be a full-circle moment for them as they opened for Shelton on his "Ten Time Crazier Tour" in 2014.

"Blake’s the best, man," Smyers said. "We’re huge fans of Blake’s music. He took us out on literally our first tour. I don’t even think we had a hit on the radio at that point. He took a chance on us…Blake, as successful as he is, is the most down-to-earth, humble dude out there, just an incredible person, incredible role model... It’s an honor to be part of his team this year."

In addition to Shelton, other coached on the new season of the voice are Kelly Clarkson, John Legend, and Nick Jonas. Luis Fonsi is set to assist Clarkson, Brandy will join Legend, and Darren Criss will team up with Jonas. Season 20 of The Voice will premiere on March 8 at 8 PM ET on NBC.
