"I haven't seen her", Bryan told ET, explaining that he and Underwood's husband, Mike Fisher, are good friends and sometimes fishing buddies.
Six months after a mass shooting at a Las Vegas country music festival, the genre's biggest stars are heading back to the city with a objective and a message beyond just country music's biggest night to party.
The song is the first Underwood will release under her new recording contract with Universal Music Group Nashville.
Carrie Underwood took to social media on Sunday night to tease fans with an image that is driving social media insane.
The ACMs will air live on CBS. After a more than a decade spent with Sony Music Nashville, Underwood switched to Universal Music Group a year ago.
The song feels especially meaningful, Bryan said, in the wake of the devastating Route 91 Harvest Festival shooting in Las Vegas last October.
"That'll be the first time that some of those artists are back in Vegas just right down the street from where the shooting happened, so it's going to be pretty emotional for some of those people like Jason Aldean", she said.
Vince Gill, who was born in Norman and grew up in Oklahoma City, also is nominated for Vocal Event of the Year for "Dear Hate", his moving collaboration with Maren Morris. He is followed by Thomas Rett with six nods.
The ACM Awards will be jam-packed with big moments, so if you're a fan of country music or just music in general, you'll want to watch the ACM Awards online or live Sunday.
Carried Underwood has shared one other photograph of her face forward of her extremely anticipated efficiency on the American Nation Music Awards.
And speaking of duets, Bebe Rexha will perform her smash hit "Meant to Be" with Florida Georgia Line on the telecast, while Julia Michaels will join Keith Urban for the song "Coming Home".
The announced presenters include David Boreanaz, Drew Brees, AJ Buckley, Cam, Sam Elliott, Eve, Ashton Kutcher, Dustin Lynch, Nancy O'Dell, Rebecca Romijn, Max Thieriot and Lindsey Vonn.
