Several collaborations are also planned, including Kenny Chesney with Dave Matthews, Vince Gill with Daughtry, and Jamey Johnson with Kid Rock.Reba McEntire, George Strait, Keith Urban, Martina McBride, Darius Rucker, Sugarland, Lady Antebellum, and Miranda Lambert are also on board to perform, along with Carrie Underwood and Brad Paisley -- who are also the show's hosts. Lee Ann Womack, LeAnn Rimes, Jake Owen, Julianne Hough, The Judds, and Kris Kristofferson are just some of the presenters lined up for the ceremony. The 43rd CMA Awards will air on ABC Wednesday at 8:00 p.m. Eastern.
