Luke Bryan and Dierks Bentley are out as ACM Awards co-hosts. The "Woman, Amen" singer spilled the news during the CRS keynote speech on Monday (Feb. 5).

Bentley and Bryan have shared co-hosting duties for two straight years, with Bryan hosting the show three times alongside Blake Shelton prior to that. It's not clear who will be filling in as 2018 hosts, or if Bryan may be hosting by himself or with another co-host.

"We did two years, I love Luke to death, he's one of my favorite people. It's hard not to have fun with Luke," Bentley said during the speech. "The ACMs were great, we had so much fun doing it. The ACMs have been so good to me."

The 2018 ACM Awards are on April 15 at the MGM Grand Garden Arena in Las Vegas. The show returns to the MGM after one year at the new T-Mobile Arena. Last year Jason Aldean was the bigger winner picking up his second Entertainer of the Year award.
