Bruno Mars made a surprise appearance at BLACKPINK’s world tour stop in Los Angeles. On July 12th and 13th (local time), BLACKPINK held their “BLACKPINK WORLD TOUR DEADLINE IN LOS ANGELES” at SoFi Stadium.

Mars joined Rosé onstage at Los Angeles’ SoFi Stadium to showcase the flirtatious track, which sees the pair dueting on vocals and sharing the hooky chorus. The musicians wore coordinating jackets for the performance, which culminated with confetti and a lively dance party from Blackpink’s backup dancers.

ROSÉ typically performs “APT.” during her solo portion of the DEADLINE World Tour setlist, but this marks the first time Mars has accompanied her for the song on the trek. After the pair dropped the track last October, it reached No. 3 on the Billboard Hot 100 and spent 12 weeks atop the Billboard Global 200.
