Before Mars stepped onstage, a message appeared on a large video screen informing the audience that the performance was being filmed for the song’s official music video.
“We’ve never performed this song live before, and today, you’ll not only hear it for the first time but also witness the recording of its music video right here with us. Are we ready?” the message read.
Karol, wearing a sparkling white dress, opened the power ballad before being joined by Mars, who donned a flower-embroidered white suit with a matching cowboy hat.
The pair then joined forces for a performance of “Still,” the opening track from Mars’ 2026 album, The Romantic . The track debuted at No. 4 on the Billboard Hot 100 in March.
Karol G recently opened up about “Still” — in which she and Mars harmonize about unconditional love despite no longer being together — in a video posted to TikTok.
“There’s a song on the album that’s entirely in English, and I don’t want people to just see it as, ‘Oh, Karol G’s new English song,’” she said. “I’ve always been open to making music in other languages — without pressure, as long as it flows and happens organically and naturally — and, well, that song found me. It expressed exactly what I was feeling and how I was feeling it; it was literally perfect for what I was going through, and I listened to it constantly. I tried to overthink it, but it was perfect — I hope it touches many people’s hearts.”
Her new star-studded 14-track album also features Drake (“Ahí”); Judeline and Rusowsky (“Bby WOW”); and Greg Gonzalez of Cigarettes After Sex (“Después de ti),” which debuted at No. 6 on the Hot Latin Songs chart earlier this year.
Karol G wraps her three-show run at SoFi Stadium on Sunday (Aug. 16), then heads to San Francisco for a two-night stand at Levi’s Stadium on Aug. 21-22. From there, she has multi-night stadium dates scheduled across the United States, Mexico, South America and Europe through July 2027.
