Underwood's "Carnival Ride," Chesney's "Just Who I Am: Poets & Pirates," and Jackson's "Good Time" were nominated for album of the year along with George Strait's "Troubadour" and Brooks & Dunn's "Cowboy Town."
Other CMA nominees included Taylor Swift and Rascal Flatts, who were on hand to reveal the some of nominees during a live announcement on Wednesday's ABC's "Good Morning America." The 18-year-old Swift, who last year won CMA's Horizon award for upcoming acts, giggled excitedly when her name was read as a nominee for female vocalist of the year, a category that included Alison Krauss, Miranda Lambert, Martina McBride and Underwood.
"I can't believe it!" Swift said. "I'm having a really good morning."
Nominees for male vocalist of the year included Chesney, Jackson, Strait, Keith Urban, and Brad Paisley.
Rascal Flatts was nominated for vocal group of the year. Other nominees in that category included the Eagles, Emerson Drive, Lady Antebellum, and Little Big Town.
Chesney was also nominated for entertainer for the year. The category also included Strait, Paisley, Sugarland and Keith Urban.
Additional nominees were to be announced later Wednesday morning in Nashville on the CMT network. The CMA awards are set for Nov. 12, and will air on 6abc.
