Pop star Bruno Mars achieved first place on a music show with his duet “APT.” in collaboration with BLACKPINK's Rosé, leaving a heartfelt message in Korean.

On October 25, Bruno Mars expressed his gratitude on social media, writing, “Thank you so much, Korean fans. I cried all morning after getting my first win on a music show.”

The song “APT.” topped the charts on the October 24 episode of Mnet's *M Countdown*. Rosé congratulated Bruno Mars with a message saying, “You did it!”

In response, Bruno Mars wrote, “Thank you so much, Rosie, for helping me achieve this first place. Thank you all for loving 'APT.' Love, Bruno oppa.”

“APT.” is inspired by the popular Korean game “Apartment.” The idea came from Rosé while she was playing the game, leading to the creation of this catchy track with a memorable hook.

Meanwhile, Rosé is set to release her first full-length album *rosie* on December 6. The album will feature 12 tracks, including the title song, with Rosé contributing to the writing and composition of every track.
