Bruno Mars is facing buzz over his surprise appearance during BLACKPINK’s Deadline tour at SoFi Stadium, L.A., on July 13. Mars joined Rosé on stage to perform their hit track “APT.” This marked his first guest performance at another artist’s concert in eight years!
Fans went wild, capturing the excitement as Bruno returned to the stage.
The controversy began when Bruno took to social media, posting backstage snaps with Rosé. He humorously captioned it, “Almost out of debt BehhhhhBehhhhh! Preciate you ROSAAAYYYYY!!” This cheeky comment references rumors he’s battling a $50 million casino debt, a claim previously debunked but still swirling online.
Soon after, fans speculated whether the collab with Rosé was a desperate attempt to “pay off” this rumored debt. His playful comment only fueled the jokes online.

Meanwhile, “APT” has been a massive hit, peaking at No. 3 on the Billboard Hot 100—the highest for a female K-pop artist. It also bagged multiple awards, including Song of the Year at the Asia Artist Awards.
Korean netizens are loving the unexpected duo. Reactions have been amusing:
“This is freaking hilarious, lol. It’s so absurd that everyone’s just laughing it off together, lol.”
“So funny. lol.”
“Freaking hilarious. lol.”
"Love his joke about his fake debt."
Fans are eager for more moments like this.



Both artists are clearly enjoying the moment, delighting fans with their chemistry and playful banter.
Is this the start of a new iconic duo?
