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.

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.

In an interview with the Las Vegas Review-Journal last summer, Mars was asked if he wanted to officially debunk the rumors himself.
