Bruno Mars co‑produces runway track

A movie trailer dropped on April 6 with a brand-new pop song in it, and by April 9 that song was out as a full single: “Runway,” performed by Lady Gaga and Doechii for *The Devil Wears Prada 2*. The extra wrinkle is in the credits. Variety reported that Bruno Mars co-produced “Runway” with Andrew Watt, Cirkut, and Dernst “D’Mile” Emile II, which means one film tie-in song pulled together four of the biggest hitmakers in current pop and rhythm and blues. 20th Century Studios used the song first as part of the movie’s final trailer, not as a separate music rollout. Disney’s trailer page says the preview features the original song and that the film opens in theaters on May 1. That matters because *The Devil Wears Prada* has always sold a world, not just a plot. The 2006 film turned magazine offices, designer clothes, and one editor’s approval into something as tense as a sports movie, so a song called “Runway” is being asked to do scene-setting work before audiences even buy a ticket. Lady Gaga is not just on the soundtrack. Deadline reported that she also appears in the sequel, so the artist behind the trailer’s biggest music cue is also inside the movie’s cast list. Doechii gives the track a second lane. Variety noted that she presented Gaga with the Innovator Award at the 2025 iHeartRadio Music Awards, and now that awards-show handoff has turned into a studio collaboration attached to a major studio sequel one year later. The production credits explain why people noticed Bruno Mars’ name so fast. Andrew Watt has recent rock and pop blockbuster credits, Cirkut has built radio hits for years, and D’Mile is one of the most in-demand rhythm and blues producers in Hollywood and pop, so Mars joining that lineup makes “Runway” feel less like merch and more like an event record built for repeat listens. Studios used to treat soundtrack songs like bonus material that arrived after the marketing campaign. Here, the campaign and the song are the same object: the trailer is the first listen, the single follows three days later, and the music is doing the job that a poster once did by telling you exactly how glossy, fast, and fashion-obsessed this sequel wants to feel.
