"I mean, this is the country music capital of the world, right?" he said to the audience before breaking into the song.
"Hold on now -- something don't feel right," he said half way through the tune. "Something don't feel right, Nashville, I mean, if you're gonna do this ... Garth?!"
Garth looked like he was super stoked to be singing his country hit with the former *NSYNC singer, too!
