Lynch told Billboard
the story of the song:
"I had that idea for a long time, and I had the guys I wanted to write that with in mind, and we got together. What started it was all the stories I get to hear people tell me backstage, and at meet-and-greets, about a song helping them through a hard time or being a part of this event in their life. That's inspiring stuff... those are songs that are fun for me to write.
'New Girl' was an idea that I just kept banging Zach and Ashley over the head about, saying 'I know this is right.' It took us six whole days [over the course of] five months or six months or something like that - we kept coming back together to write. It's definitely a song I'm proud of because it's a reminder every time I sing it that the people in my life are the best for me."
