We already knew that Miranda Lambert was among the list of performers for the 2014 CMA Awards, but now it seems the songstress is getting a duet partner. In what perhaps will be one of the most anticipated pairings of the evening, Lambert will take the stage with pop star Meghan Trainor, performing Trainor's biggest hit.

Trainor, who resides in Nashville, soared to the top of the charts with her multi-platinum tune, 'All About That Bass,' earlier this year. Lambert will perform the song with Trainor, putting her own spin on the 20-year-old's song about embracing a healthy body image.

Trainor isn't the only pop star who will take the stage during the three-hour show. Ariana Grande will also sing with brand-new Opry members Little Big Town.

Other performers for the night include Jason Aldean, Dierks Bentley, Kenny Chesney, Tim McGraw, Luke Bryan, the Band PerryLady Antebellum, Blake Shelton and Keith Urban. Hosts Brad Paisley and Carrie Underwood will also perform.

Lambert is the most-nominated artist of the night with nine nods, including the night's highest honor, Entertainer of the Year. See a complete list of nominees here.

The 2014 CMA Awards will air live from Nashville's Bridgestone Arena on Wednesday, Nov. 5 at 8PM ET on ABC.
