In a recent interview with PEOPLE, Hunter talked about his second big hit and admitted who the song is about!
"She knows the song is about her, and I give her a hard time, but we laugh about it now," he said not giving away the girl's name.
"I knew it wasn't going to work because she wasn't into the relationship thing, but I wanted to try anyway," he said.
"The song was an attempt to say, 'Let's see how it goes. I know I'll probably get bummed out, but I will take any time with you.'"
Hunter also admitted their split wasn't as bad as it might seem.
Either way, we wonder who the lucky girl is and what happened between the two of them?!
