The 2014 ACM Awards are less than a week away, and now even more performers have been added to the three-hour broadcast.

The Band Perry have been announced as the evening's opening act, performing their latest single, 'Chainsaw,' to begin the red carpet show.

Hunter Hayes, who is kicking off ACM Week with a show at the LINQ on Thursday (April 3), will also perform his latest single, 'Invisible,' as part of the ConAgra Foods’ Child Hunger Ends Here campaign. Hayes will continue his partnership with the company later this year, when he attempts to break a world record for the most shows played in 24 hours, as part of his 24 Hour Road Race to End Child Hunger.

Luke Bryan, who is co-hosting the show along with Blake Shelton, will also take the stage to sing. The Georgia native will perform with Florida Georgia Line for their single, 'This Is How We Roll,' along with Nitro Circus’ action sports stars.

Miranda Lambert earned perhaps the most coveted performance slot of the night. The songstress will perform with George Strait as part of a medley to honor Merle Haggard's legendary 50-year career. Their duet will be followed by Garth Brooks, who will present the Hag with the Crystal Milestone Award on his 77th birthday.

Previously-announced performers for the live telecast include Eric Church, Toby Keith, Keith Urban, Jason Aldean, Blake Shelton and Lady Antebellum, who will perform with rocker Stevie Nicks.

The 49th annual ACM Awards will air live from Las Vegas on Sunday, April 6, at 8PM ET on CBS. See a complete list of nominees here.
