Bruno Mars performs APT with Rosé during Blackpink’s Deadline World Tour stop in Los Angeles

Grammy-winning artist Bruno Mars made a surprise appearance during Blackpink’s Deadline World Tour, joining Rosé onstage at Los Angeles’ SoFi Stadium for a performance of their joint single “APT.” The moment unfolded during the group’s second Los Angeles show over the weekend and marked a standout highlight in the U.S. leg of the tour.

Following the high-energy performance, Blackpink—made up of Jisoo, Jennie, Rosé, and Lisa—continues their 31-date world tour, which began on July 5 in Goyang, South Korea. The tour is the group’s first all-stadium run and spans major cities across Asia, Europe, and North America. It will conclude on January 25, 2026, at Kai Tak Stadium in Hong Kong.

Rosé and Mars, both dressed in matching jackets, thrilled fans with their performance, closing the set with confetti and an upbeat dance party featuring Blackpink’s backup dancers. The moment quickly went viral on social media, with fans praising the duo’s chemistry and showmanship. One user on X (formerly Twitter) dubbed it the “collaboration of the year,” while another pointed out that it was Mars’ first guest appearance at another artist’s concert in eight years.
