Rumors about collaboration started when Florence shared an Instagram picture of her standing in front of a baby blue Ford Bronco – the same custom car Gaga was photographed driving earlier the same week. They were also both spotted with Mark Ronson in California. During an interview with BBC1 Radio, Gaga spoke about the collaboration on the album, "There's a feature on the album that I think you will be very excited about. Me and Florence Welch did a duet together. I started to work on an idea for a song that I really wanted to do with a girl. You’ll see why when you see what the song is about." She continued, "I just thought, ‘Who do I want to sing with?’ She’s really to me if not the best, one of the greatest vocalists in the world. She’s incredible." During and interview with Beats1, Zane Lowe has asked her about the making process of the song and she replied: "Love that record. [...] I remember when she [Florence] came in and I was like o.k. I want to go back and forth [...] and she was like "Why are we going back and forth [...] I should just sing the second verse in this" and I was like "No! [...] There's got to be a conversation. We got to talk to each other. I need to women having it out and the coming together""
- During the encore of the Joanne World Tour performance in Denver, Gaga sang a snippet of "Hey Girl" to a fan. The lyrics she sang were: "Hey girl, can you hear me? Are you holding out your heart?"
- The recording session of "Hey Girl" between Welch and Gaga was featured in the Netflix documentary Gaga: Five Foot Two. It took place at Mark Ronson's house.
