From country music's favorite husband-and-wife duo to some brand-new faces, the nominees for Vocal Duo of the Year at the 2018 ACM Awards cover the spectrum of country music. Who's your pick?

Brothers Osborne won both New Vocal Duo of the Year and Vocal Duo of the Year last year at the ACMs. Still riding on the success of their 2016 debut Pawn Shop, the brothers are set to release a new album, Port Saint Joe, in April, that promises more of the same. Dan + Shay are back in the nominee lineup this year, and their latest single "Tequila" is making its way up the charts ahead of a new album out later this year.

Florida Georgia Line are breaking chart records once again with their new pop collaboration with Bebe Rexha, "Meant to Be," and show no signs of losing momentum anytime soon, although up-and-coming LoCash might be hot on their heels. The duo behind "Ring on Every Finger" is also in the running for New Vocal Duo or Group of the Year. Also this year, Tim McGraw and Faith Hill stake a claim in the list of nominees for their work together on the Soul2Soul Tour, their latest hit "The Rest of Our Life" and their duets album of the same name.
