With just under two months left until the 2015 CMA Awards air on Nov. 4, several of the nominees for "Country Music's Biggest Night" were revealed on ABC's Good Morning America Wednesday morning (Sept. 9). The rest were announced on the CMA website shortly thereafter.

Steven Tyler and breakout singer-songwriter Kelsea Ballerini helped announce the final nominees in all 12 categories live from Times Square. Ballerini was nominated for two awards herself, exclaiming, "That's not real!" upon hearing of them.

This year's nominees are a mix of the biggest names in country -- Luke Bryan, Carrie Underwood, and Garth Brooks -- and some of the genre's hottest newcomers, such as Sam Hunt, Maddie & Tae, and Chris Stapleton. For the eighth consecutive year, Underwood and Brad Paisley will serve as the show's co-hosts when it airs live from Nashville's Bridgestone Arena on Nov. 4 at 8pm.
