Gwen Stefani wrote the lyrics about her boyfriend Blake Shelton. The pair found love after their divorces from Gavin Rossdale
and Miranda Lambert respectively.
Stefani told Jimmy Kimmel how music helped her cope with the situation. "What's so crazy is that sometimes tragedy, if you really absorb it, you can turn it into something beautiful," she explained. "And this whole album is really about trying to take something awful and healing from it and turn it into something beautiful."
