Six additional country stars have joined the 2016 American Country Countdown Awards performance lineup: Kelsea Ballerini, Cam, Dan + Shay, Sam Hunt, Martina McBride and Cole Swindell will all take the stage during the upcoming awards show.

McBride and Swindell are not among the 2016 ACC Awards finalists, but Ballerini, Cam, Dan + Shay and Hunt have all earned nods in multiple categories: Ballerini and Cam are nominated for Female Artist of the Year and Breakthrough Female Artist of the Year, while Dan + Shay are up for Group / Duo of the Year and Breakthrough Group / Duo of the Year. Hunt, meanwhile, received five noms, in categories including Artist of the Year, Male Vocalist of the Year and Album of the Year.

Although they're not ACC Awards finalists, McBride and Swindell both have new music coming out around the time of the awards ceremony: McBride's Reckless is set for release on April 29, while Swindell's You Should Be Here will drop on May 6.

These six artists join a performance lineup that already includes Luke Bryan, Florida Georgia LineThomas Rhett and Carrie Underwood.

After being postponed late in 2015, the American Country Countdown Awards are set to return on May 1. The show will air live on Fox from 8PM ET until 10PM ET, from the Forum in Inglewood, Calif. The two-hour awards ceremony will be the first country music awards show to air live from Los Angeles in more than 10 years.
