Why Garth Brooks and Trisha Yearwood Will be 'The Happiest Couple' at the ACM Awards

The singer reveals the advice his wife gave him about Sunday's ceremony.

Since then, he has gone on to play his 100th show on the trek, with ticket sales topping the two-million mark.

"The talent level is crazy, and again, there's five names in there we can name," he told ABC News. "Keith [Urban], Blake [Shelton], Eric [Church] -- you could name, there's guys that should be in there as well that aren't, so this is gonna be a tough category to walk away with it."

"My wife said, 'Do me a favor. Let's go there with no expectation. Let's be the happiest couple in the room, and let's have fun,'" he said. "I don't know if an award show I've ever done that, 'cause [with] awards shows, you're always nervous and everything, but this one -- I'm just gonna go there and have fun."

"Her schedule is a lot more hectic than mine," Brooks marveled. "I'm just gonna come there and play music and have some fun!"
