Last month, Lady Gaga performed at the opening ceremony of the Summer Olympics in Paris. Although she is busy with Joker: Foil for Twoshe is back in music mode today with a new collaboration with Bruno Mars called “Die With A Smile.”

The pop stars co-produced “Die With A Smile” with Andrew Watt and D’Mile, and those four are credited as writers on the song along with James Fauntleroy. Gaga and Mars promoted it by wearing each other’s T-shirts on Instagram. In her post about the song, Gaga teased her next album, due out next year, writing: “WHILE YOU WAIT FOR LG7…”

“Bruno and I have a lot of mutual respect and we talked about working together,” Gaga says of the collaboration. “I was finishing up my own album in Malibu and one night after a long day he asked me to come to his studio to listen to something he was working on. It was about midnight when I got there and I was blown away when I heard what he had started doing. We stayed up all night writing and finishing the song. Bruno’s talent is indescribable. His musicianship and vision are on a whole new level. There is no one like him.”

Mars adds: “It was an honor to work with Gaga. She is an icon and brings magic to this song. I’m so excited for everyone to hear it.”
