Jason Aldean’s next single will be a duet with Carrie Underwood called “If I Didn’t Love You.” He teased the song on social media on Wednesday (July 21st) writing, “We’ve got a brand new song coming your way this Friday! Who do y’all think is singing on this one with me?” Carrie replied simply with an emoji of her raising her hand. “If I Didn’t Love You” is out today (Friday, July 23rd).
