ROSÉ surprised fans at Bruno Mars’ Los Angeles concert on Wednesday, Oct. 7, when the BLACKPINK singer appeared on the stadium’s big screen during the “Angel Baby Cam” segment of his The Romantic Tour.
The moment took place at SoFi Stadium in Inglewood, California, during the final Los Angeles show of Mars’ current tour stop. Rather than joining the singer onstage, ROSÉ was spotted among the audience as the camera scanned the crowd during “God Was Showing Off,” a playful segment in which Mars serenades people featured on the screen.
ROSÉ embraced the moment by dancing, smiling and blowing kisses toward the crowd as thousands of fans cheered. Her appearance quickly became one of the concert’s most talked-about moments, with clips spreading across social media shortly after the show.
The crowd’s reaction grew even louder when fans began chanting along to “APT.,” the hit collaboration released by ROSÉ and Mars in October 2024. The brief sing-along turned the cameo into a moment celebrating the pair’s musical partnership, even though they did not perform the full song together during the appearance.
“APT.” became a global hit, combining pop-rock production with a chant inspired by a Korean drinking game. The song debuted at No. 8 on the Billboard Hot 100 in November 2024, giving ROSÉ her first solo top 10 on the chart and marking another major success for Mars, who had already established a lengthy history of chart-topping collaborations.
The track continued to perform strongly on streaming platforms and international charts, helping expand ROSÉ’s profile beyond her work with BLACKPINK. It also became a defining release in her solo career following the launch of her debut studio album, rosie, in December 2024.
Mars’ Los Angeles concerts are part of The Romantic Tour, supporting his fourth studio album, The Romantic, released in February 2026. The album marked his first solo studio release since 24K Magic in 2016 and debuted at No. 1 on the Billboard 200.
The singer’s current show combines material from the new album with established hits such as “24K Magic,” “Treasure,” “That’s What I Like” and “Uptown Funk.” The “Angel Baby Cam” has become a recurring feature, giving fans unexpected moments of attention during the performances.
ROSÉ has also been continuing her solo activities following the success of rosie. In September 2026, she released “New Trick,” beginning a new chapter after the international success of “APT.” The new single follows her work with Mars and her continued activities as a member of BLACKPINK.
The appearance at SoFi Stadium brought renewed attention to the artists’ collaboration and their ongoing friendship. While ROSÉ did not join Mars for a full live performance during the cameo, the audience’s spontaneous sing-along to “APT.” highlighted the lasting popularity of the song nearly two years after its release.
