Landing in five categories each, Maren Morris and Thomas Rhett are among the leading nominees for the 55th ACM Awards. Nominations were revealed early this morning on social media. Hosted by Keith Urban, the all-star event will air live from the MGM Grand in Las Vegas on Sunday, April 5 on CBS.

The Academy of Country Music also recognized Justin Bieber, Dan + Shay, Old Dominion and Blake Shelton with four nominations each, although members of Dan + Shay and Old Dominion secured additional nods as individuals. (Technically, because Dan + Shay's Dan Smyers has a production credit and songwriting credit on "10,000 Hours," he's up for six awards, making him the leading nominee overall.)

Among songs, "10,000 Hours" appears in four categories, while Shelton's "God's Country" and Old Dominion's "One Man Band" settle into three spots each. Morris places her fifth nomination this year as a member of The Highwomen, which also features Brandi Carlile, Natalie Hemby, and Amanda Shires in its lineup.

Producer Dann Huff, also a five-time nominee, is noted for his work with Brantley Gilbert and Lindsay Ell, Lady Antebellum, and Thomas Rhett. In addition, he lands in the Guitar Player of the Year and Producer of the Year categories. Brooks & Dunn and Billy Cyrus are back on the ballot after long absences, too.

Meanwhile, Luke Bryan makes his eighth appearance in the Entertainer category, a trophy he's claimed twice. Carrie Underwood returns in that spot with her fourth nomination, including two wins. However, it's only the second time Eric Church has been nominated for the biggest award of the night, and the first Entertainer nod for Luke Combs and Thomas Rhett. Urban won the award in 2019.
