Rosé and Bruno Mars Hint at Another Duet Following Global Smash ‘APT.’

BLACKPINK’s Rosé and global pop superstar Bruno Mars have officially confirmed that their collaboration goes beyond their chart-topping hit “APT.”—revealing that an additional unreleased duet already exists, sending excitement rippling through the global music community.

The confirmation came during Rosé’s recent Billboard cover interview, where the two artists reunited to discuss the creation of “APT.,” widely recognized as one of the most successful global songs of the decade. When asked directly whether they had worked on other songs together, Bruno Mars responded unequivocally, stating that another track does exist and that both artists are carefully considering how and when it should be released.

Released in October 2024 as the lead single from Rosé’s first full solo album rosie, “APT.” became a historic crossover moment. The song dominated international charts, topped both the Billboard Global 200 and Global Excl. U.S. charts, and accumulated billions of streams worldwide. Its success also led to Rosé earning three Grammy Award nominations, including Song of the Year, marking a groundbreaking milestone for a K-pop solo artist.

Beyond its commercial impact, the Billboard interview revealed the depth of creative trust behind the collaboration. Rosé shared that Bruno Mars played a key mentorship role during her transition into her solo career, offering guidance not only on “APT.” but throughout the album’s development. Mars also co-wrote and co-produced rosie’s opening track, “Number One Girl,” further cementing his involvement in the project.

Bruno Mars, in turn, highlighted how “APT.” introduced him more deeply to Korean culture, noting that the song’s roots in a Korean drinking game and Rosé’s cultural perspective were central to its authenticity. He described the experience as creatively rare, emphasizing that the collaboration felt culturally meaningful rather than formulaic.

While details surrounding the unreleased song remain under wraps—including its title and release timeline—the confirmation alone has fueled speculation among fans worldwide. Many are now wondering whether the track could surface as a future single, a special release, or part of a new project altogether.

With “APT.” already redefining what global pop collaboration can look like, anticipation is building for what Rosé and Bruno Mars might unveil next. For now, one thing is certain: their musical partnership is far from over—and the world is listening.

Bruno Mars’ candid response when asked whether the two had worked on additional music after “APT.” His answer was short—but explosive. Yes, another song exists. He described it as a “really good” track, adding that while the title and release plans remain undecided, the song is very much real.

Bruno Mars also noted that working on “APT.” introduced him more closely to Korean culture and the passion of K-pop fans worldwide, an experience he described as creatively energizing. Rosé echoed that sentiment, highlighting the trust and emotional connection that developed during their collaboration.

With one of the most successful cross-genre collaborations in recent years already under their belt, the confirmation of another unreleased duet has only intensified anticipation. Whether the song arrives in 2026 or sooner, fans around the world are now watching closely, waiting for Rosé and Bruno Mars to reunite—and possibly redefine global pop once again.
