Though you don't have to be her boyfriend for her to write songs about you. She wrote a song about Alan Del Rio. Though while not in a relationship they've been friends since they were kids so unless you have a time machine that's out of the question too.
Carrie and her were sending song stuff back and forth when they were together and she's thanked on the new album.
