INTERVIWER: And [Swedish mega-producer] Max Martin worked on that song too, right?
SELENA: Yes, he did. How it happened was we were in the studio working with a few producers that have worked with Max [Mattman & Robin, on Taylor Swift’s 1989]. That’s how we created the skeleton of the track in the studio. When we had the hook, they were like, “Do you mind if we send this to Max Martin?” I had never worked with Max before and was like, “I don’t know, maybe!” I just didn’t know what it was going to be. He ended up FaceTiming immediately and was like, “This is the greatest thing I’ve heard all year. I have to be a part of it.” I’m like, “Yeah! Do what you’ve got to do! What do you suggest?” He came up with the very end where it goes se-eh-eh-eh-eh-eh-elf and added that little hook. He also changed some of the pre-chorus. I think it is super fresh and different for him, too.
