The ACM Awards are the spring's hottest country awards show, and this year, there's no shortage of performers, from country legends to fresh-faced newcomers, set to light up the stage.

Alan Jackson, Martina McBride, Brad Paisley, Lady Antebellum and Little Big Town are also slated to perform ... and there are two interesting duets set to occur, pairing decidedly non-country stars with country artists, similar to Shelton and Shakira's "Medicine" performance from last year's ACMs. Christina Aguilera — now a Nashville guest star — will duet with Rascal Flatts, and Dan + Shay will perform with pop singer Nick Jonas.

As the cherry on top of a lip-smacking lineup, Brooks & Dunn — the recipients of a whopping 27 ACM trophies — will give their first televised performance together since 2010. If that isn't a stacked performance list, we don't know what is. The ACM Awards will certainly be celebrating their 50th anniversary with some of country's biggest names and brightest stars.

Which performance are you most looking forward to? Vote as often as once per hour until the beginning of the show. You’ll be able to catch all of the performances live during the broadcast, and be sure to check back to The Boot for complete coverage of all the action throughout the night.

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