KAROL G, Bruno Mars – Still

Bruno Mars’s surprise appearance was announced to the crowd before he walked out

A few weeks before her sixth album arrived, Karol G posted a video asking people not to do the obvious thing with one of its tracks. She did not want it filed as her new English song, she said, because the song had found her rather than the other way round, and because it described precisely what she was going through at the time. The track is Still, it sits sixth on No Me Arrepiento de Sentir Tanto, and it is the only song she has recorded entirely in English.

Her label released the album on August 7, 2026. Still is a ballad rather than anything built for the dancefloor, and Bruno Mars wrote it with the writing and production team he has worked with for years, which is a substantially different arrangement from a featured guest dropping in for sixteen bars. The two of them share it rather than trading it.

The surprise everybody was told about in advance

On August 15, 2026, Karol G played the second of three sold-out nights at SoFi Stadium in Inglewood, California, on the Viajando Por El Mundo Tropitour. Before Mars appeared, a message went up on the stadium’s video screen telling the audience that the song had never been performed live, and that they were about to hear it for the first time and watch its music video being recorded at the same moment. Then Mars walked out, in a white suit embroidered with flowers and a matching cowboy hat, to join Karol G in a white sparkling dress, in front of more than fifty thousand people.

So the surprise was genuine for the crowd and entirely scheduled for everyone on the production side. Mars had taken a detour from his own stadium tour to be there. The audience found out they were the video roughly ninety seconds before they became it, which is a strange thing to be told in a football stadium, and their reaction is part of what the cameras were there to capture.

Black and white until the stage

The video arrived on September 2, 2026, and the performance is not most of it. Cameras had been running for hours before the doors opened, and that footage is what the film is built from: the two of them in the empty lower bowl seats, passing lines of the song back and forth to nobody; a moment in the dressing room; a ride on a utility cart through the concourse; Mars with a guitar backstage. All of it is in black and white. The color arrives only when they reach the stage.

That structure is doing something more deliberate than a stylistic flourish. The monochrome section is two musicians who have made a record together getting comfortable in an empty building, and the color section is fifty thousand people finding out about it. It also quietly solves the problem Karol G had raised on TikTok. A video that spends most of its running time on rehearsal rather than spectacle is not a crossover announcement. The scale is available if anyone wants it — her 2023 Rose Bowl run made her the first Latin artist to sell out two consecutive nights there, taking $25.4 million from 120,000 people, and the current tour runs through July 2027 with a US stadium finale at AT&T Stadium in Arlington on October 15, 2026.

What the film ends up being about is the hours nobody bought a ticket for. The performance is four minutes of an event that fifty thousand people attended and that has been widely photographed. The empty stadium is the part that only existed because someone kept the cameras running before there was anything to film, and it is the reason the video holds up on a second watch. The surprise was the announcement. The song was the afternoon.
