Grammy-winning Lady Antebellum and classic rocker Stevie Nicks were such a hit during their 'CMT Crossroads' collaboration, they're taking their partnership to the 2014 ACM Awards stage.

The collaboration is an addition to an already star-studded performance lineup.

Other just-added performers include country rocker Eric Church and 'I Love This Bar' hitmaker Toby Keith. Of course, none of these acts are strangers to the ACM stage. At last year's ACMs, Church performed 'Like Jesus Does,' while the harmonious Lady A trio brought 'Downtown' to the stage.

Jason Aldean, Luke Bryan, Miranda Lambert, Blake Shelton, George Strait, Keith Urban, Florida Georgia Line and the Band Perry will also perform at the 2014 ACMs. Additional acts and presenters will be announced in the coming weeks.

The 49th Annual Academy of Country Music Awards, co-hosted once again by Bryan and Shelton, will be broadcast live on CBS from the MGM Grand Garden Arena in Las Vegas on Sunday, April 6, 2014 at 8PM ET.
