With the 2015 ACM Awards just days away, the Academy of Country Music has announced the list of presenters for the 50th anniversary ceremony.

Among the names are numerous country stars, including Clint Black, Lee Brice, Kelly Clarkson, Brett Eldredge, Brantley Gilbert, Mickey Guyton, Hunter Hayes, Justin Moore, Jake Owen, Thomas Rhett, Darius Rucker, Keith Urban, Trisha Yearwood, Dwight Yoakam, Alabama and Big & Rich. Football players Troy Aikman, Tony Romo and Jason Witten; actresses Beth Behrs, Sofia Vergara and Reese Witherspoon; Miss America 2015 Kira Kazantsev; Taya Kyle, widow of U.S. Navy SEAL Chris Kyle; Dr. Phil McGraw and Nancy O'Dell are also scheduled to present awards during Sunday night (April 19)'s awards show.

The final presenter announced was Steven Tyler, who recently signed with Big Machine Label Group and is working on his debut country album, as a solo artist.

“My earliest influences put me somewhere between the Everly Brothers and the Carter Family, and this project is all about me paying homage to my country roots," Tyler says of the upcoming release.

It will be a busy weekend for many of the artists on the presenters list: Brice, Rhett and Urban are each nominated for an ACM Award this year (Single Record of the Year, New Artist of the Year and Song of the Year, respectively), and Rhett and Urban are also scheduled to perform during the broadcast. Alabama, Rucker, Yoakam, Gilbert, Black, Hayes, Eldredge, Urban and Owen will take part in the ACM Party for a Cause on Friday and Saturday (April 17-18) as well -- during which Rhett will be playing a life-size game of checkers -- and Yearwood and husband Garth Brooks will be hosting a charity gala for ACM Lifting Lives, at which Urban and Hayes will be performing.

The 2015 ACM Awards will air live from AT&T Stadium in Arlington, Texas, on April 19 at 8PM ET on CBS.
