The tall singer from Louisiana with the imposing presence and booming voice also will perform during the inaugural show on Dec. 6 at the MGM Grand in Las Vegas, which airs on Fox.
The assignment will help Adkins expand an ever-growing resume that includes actor, reality TV star and even comic book hero.
Adkins picked up Country Music Association and Academy of Country Music awards this year for his "Hillbilly Bone" collaboration with Blake Shelton.
Organizers of the fan-voted award show also added performances by lead nominee Easton Corbin, who is tied with Lady Antebellum at seven, and Steel Magnolia and Uncle Kracker.
