Bruno Mars owes a debt of gratitude to ROSÉ for letting him perform “APT.” with her at a recent BLACKPINK tour stop. In a post about the performance on Instagram, the American singer-songwriter thanked his duet partner and joked that the stint had helped him pay off his long-rumored gambling debts.

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.

Bruno Mars makes a lighthearted remark about a past rumor that he racked up more than $50 million in gambling debt during his Las Vegas residency with MGM Resorts.
