“APT.” by Rosé and Bruno Mars won International Song of the Year at the 2026 BRIT Awards. The collaboration was one of the defining global pop releases of 2025 and became a major streaming and chart success.
The song takes its title from “apartment,” referring to a Korean drinking-game chant. Rosé introduced Bruno Mars to the game, and its repetitive “apateu” hook became the song’s central musical and lyrical idea. The track combines Rosé’s K-pop background with Mars’s pop, funk and soul influences.
The award was especially notable because it marked Rosé’s first BRIT win and the first BRIT Award for a K-pop artist. The title is sometimes written as “APT” or “APT.”, but the stored answer identifies the correct song. It should not be confused with “Die with a Smile,” another Bruno Mars collaboration and a listed nominee.
