The Academy also says in a Tuesday news release that this year's show will be held April 7 and Brad Paisley will host the ACM Fan Jam, a satellite event held simultaneously with the awards show.
Bryan replaces Reba McEntire. She served as host for more than a decade before stepping aside to concentrate on her new sitcom "Malibu Country."
Shelton is also a star on "The Voice" and began sharing hosting duties with McEntire two years ago. This will be Bryan's first gig hosting a live event.
The 48th annual ACM Awards will be broadcast live on CBS from the MGM Grand in Las Vegas.
