Aerosmith rocker Steven Tyler and rising country music star Kelsea Ballerini made an appearance on Good Morning America to announce the nominees for the 2015 Country Music Association Awards (CMAs), ABC reported. Country artists Eric Church and Little Big Town are both tied for the most award nominations.

Tyler and Ballerini took turns reading off the list of nominees in the most coveted categories. Tyler read off the nominees for CMA New Artist of the Year which included Ballerini. She responded with excitement.

 "Oh my god, wow!" she said, and high-fived Tyler. "Yes!"

But it was the CMA Female Vocalist of the Year category that shocked her the most. When Tyler read off the list for the ladies nominated for the award, Ballerini's was last and she reacted with disbelief.

"No, that's not real. That's not real! Oh my gosh!" she shouted as Tyler showed her the proof. She's going head-to-head with female country megastars like Miranda Lambert, Kacey Musgraves, Carrie Underwood, and Lee Ann Womack.

When GMA host Robin Roberts asked Ballerini how she felt now that she's nominated for two awards, she responded humbly.

"I'm shaking," she said. "I sat at the CMA awards as a fan last year, like what is this? I am so excited, oh my gosh."

The Male Vocalist of the Year award nominees are Dierks Bentley, Luke Bryan, Blake Shelton, Chris Stapleton and Eric Church. Church is also nominated for Entertainer of the Year, Single of the Year, Song of the Year and Musical Event of the Year.

He's tied for most nominations with the group Little Big Town, which is up for Vocal Group of the Year, Musical Event of the Year, Song of the Year, Music Video of the Year, and Single of the Year.
