On July 14, BLACKPINK wrapped up their two-night DEADLINE World Tour stop at SoFi Stadium in Los Angeles, drawing nearly 100,000 fans and continuing their record-breaking streak.
But the real surprise came during the second night, when Bruno Mars made a jaw-dropping appearance as Rosé’s special guest, instantly setting the internet ablaze. The global pop icon lit up the stage alongside Rosé with an electrifying performance of his billion-view hit APT., thrilling fans without elaborate choreography or flashy effects—just raw energy and charisma.
Rosé later took to Instagram to share behind-the-scenes footage and photos with Bruno, showing the pair laughing and even playing a game of tower-stacking in the green room. Their chemistry was undeniable onstage, and fans couldn’t get enough of their adorable friendship.


Poking Fun at Debt Rumors
One moment that particularly delighted fans was Bruno Mars joking in the comments: “Almost out of debt BehhhhhBehhhhh, Preciate You ROSAAAAYYYYYY.”
The remark was widely interpreted as a humorous jab at the gambling debt controversy that resurfaced last year.

Previously, U.S. media outlet NewsNation reported that Bruno Mars allegedly racked up $50 million (approx. 69.5 billion KRW) in gambling debt at MGM Grand Casino. The outlet claimed that “MGM essentially owns Mars” and that while the singer earns $90 million (approx. 125.2 billion KRW) annually, most of it goes toward taxes and debt payments.
However, MGM quickly shut down the rumors, stating, “We’re proud of our partnership with Bruno Mars, one of the most dynamic performers in the world. Our relationship spans many years and is built on mutual respect. Any suggestion otherwise is completely false.”
This isn’t the first time Bruno Mars has addressed the speculation with humor. Back in January, when he surpassed 150 million monthly Spotify listeners, he wrote, “Keep streaming. I’ll pay off that debt soon!”
Matching Looks and On-Stage Chemistry
This concert marked Bruno Mars’s first guest appearance in eight years, prompting his fanbase to flood social media with gratitude toward Rosé for making the impossible happen. Many joked that Rosé’s “superpower” was pulling Bruno out of the glitzy casinos of Las Vegas and back onto the concert stage.

To top it off, the duo sported matching leather jackets, rumored to be a gift from Bruno purchased in Japan for Rosé. Fans also noted that Bruno has consistently coordinated his wardrobe with Rosé across multiple appearances, from punk-rock vibes in the APT. MV to sleek suits at the MAMA Awards.
Their stunning visuals, synchronized outfits, and genuine affection had fans joking that the duo looked more like lovers than collaborators. Rosé’s fans even dubbed her “the exception” in Bruno’s world, especially since he playfully refers to her as his “younger sister” and now openly embraces his “oppa” title among K-pop fans.

In turn, Bruno is one of the rare male stars Rosé interacts with publicly. She frequently posts about him, expresses her admiration in interviews, and shows sincere appreciation for his support.
Their artistic connection and mutual respect have become a source of joy for global music fans. Now, fans are manifesting another collaboration between the two superstars, hoping their friendship blossoms into even more chart-topping music in the near future.
