Blake Shelton, Luke Bryan, Little Big Town, Montgomery Gentry, Craig Morgan, Brett Eldredge and Sunny Sweeney will perform a free, private USO show for Nellis Air Force Base troops and their families. Hosted by the Academy of Country Music and the USO for the second consecutive year, the concert takes place April 2 as part of 'The Week Vegas Goes Country.'

Blake Shelton has additional plans while at Nellis Air Force Base. Blake will host the first-ever NRA Country/ACM Celebrity Shoot. The event is a 13-station, 50-target sporting clays competition for 20-26 teams of five shooters with a celebrity captain. Prizes will go to the top three teams.

"We get to do something we love to do, with our fans, and help raise awareness for a worthy cause while having a great time," Blake says.

Blake's also co-hosting the ACMs with Reba McEntire Sunday evening; a fact that had producers on edge at first, due to the 'Hillbilly Bone' singer's unique sense of humor. "I cut them right off and tell them, 'Guys, don't worry about it,'" he says. "They're a little worried, but I think that makes them excited at the same time."

GAC's Storme Warren returns to emcee the ACM/USO performance, which is open to all military ID holders. The ACM Awards air live from Las Vegas April 3 at 8:00 PM ET/delayed PT on CBS.
