It's that time of year again in Sin City: Country music is taking over Las Vegas for Sunday's (April 15) 2018 Academy of Country Music Awards. Many stars have already descended on the town to prep for the big event, which will feature more than two dozen artists performing live.

There are plenty of parties and fun events leading up to Sunday night, but there's a lot of work to be done, as well. To that end, Jason Aldean, Kelsea Ballerini, Luke Bryan, Thomas Rhett, and many more have all been spotted taking care of business at their rehearsals and pre-show interviews. Get a glimpse of the behind-the scenes action with the gallery above.

The 2018 ACM Awards will air live on CBS beginning at 8PM ET. The ceremony will take place at the MGM Grand Garden Arena. The show will be hosted by Reba McEntire.
