Bruno Mars teases another collaboration with BLACKPINK’s Rosé after APT. success

Bruno Mars and Rose song APT bagged three Grammy nominations

Bruno Mars and a BLACKPINK member, Rosé, collaborated on the popular song, APT. The song instantly became an internet sensation. However, the singers have teased that they will collaborate on another project.

In a recent interview with Billboard, which was released on December 11, 2025, Bruno Mars and Rosé revealed that they have collaborated on tunes other than their huge hit APT.

Rosé laughed knowingly when asked if they had collaborated since the album's release or if they had worked on other songs that were left off of her debut album, "Rosie."

Bruno Mars then confirmed the news and said, "Oh, yeah, there is. And we love that song that we worked on — I won't say the title... We're just trying to figure out when, or how."

Rosé and Bruno Mars' first collaboration, APT. became one of the popular songs of 2025. A straightforward Korean drinking game in a Los Angeles studio in 2024 served as the impetus for the team's collaboration on the huge smash "APT." The group spontaneously chanted the now-famous hook after Rosé taught the group her favourite game, "Apartment" (pronounced apateu), during a session with producers and songwriters.

Despite Rosé's initial reluctance to release a song based on a drinking game—she even asked her team to remove it from their phones—the song eventually made its way to Bruno Mars after she presented him with three possible tracks for a joint project.

Rosé became the first lead K-pop artist to be nominated in all six major Grammy categories with APT. earning three nods, including Song of the Year and Record of the Year. Another first for a K-pop artist, the song took home Song of the Year at the 2025 MTV Video Music Awards.
