The song was written by James Slater (Rascal Flatts' "Unstoppable
"), Chris Tompkins ( Carrie Underwood's "Before He Cheats
") and Mark Irwin (Tim McGraw and Taylor Swift's "Highway Don't Care
"). Slater recalled the day that the threesome penned the song. "I had never written with Chris Tompkins before, but I've always wanted to," he told Roughstock
. "We're both piano players, and I've always loved his wit and his writing. Mark Irwin had been writing with him for a long time. Mark is a great guy, and he and I started writing together. He said, 'You need to write with Chris Tompkins and me.' I was like, 'Let's do it!' So I've got to give Mark credit for setting the three of us up. It was pretty much one of those magical days where we walked in and it all came together."
"I think I had an idea, but it wasn't really fitting anything," Slater continued. "If I remember right, Chris had this loop going on his drum machine, and he goes, 'I've got an idea.' He had this thing called 'That Girl.' We started on that, and it was such a great idea. We worked on it and worked on it, and we finished it all that day. We really had fun with the lyrics. We were really trying to make it where someone like Tim could cut it. We wanted it to be really lyrically strong."
"A couple of days later after we demoed it," added Slater, "Chris played it for Florida Georgia Line, and they liked it a lot. Then, somehow Tim heard it, and he wanted to cut it. Thanks to Byron Gallimore ... he produced the heck out of it, and Tim sang it great."
