Lady Gaga and Mark Ronson wrote the song at the same they were crafting her 2016 album Joanne
. "As soon as her and Bradley got into the film, the entire Joanne
album just turned into A Star Is Born
for a couple of weeks," Ronson told Billboard
The pair originally wrote it as an Ally solo song, just for Gaga to sing, and Ronson didn't conceive it as a duet. "I certainly never realized it was going to be part of the plot, the narrative in the parking lot, which is really such a beautiful scene," he said.
