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.

American pop star Bruno Mars showed off his sense of humor. Mars posted a message on his personal account on the 15th, "Almost out of debt Behhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh!!! Preciate You ROSAAAYYYYYYYYYYYYYYYY!

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.
