Mars shouted, "Ladies and gentlemen, big bad Rosie!" to the crowd after Rosé kissed his cheek, setting a club-like vibe that kicked off music's biggest night. The duo snagged nominations for Record of the Year, Song of the Year, and Best Pop Duo/Group Performance, though they didn't take home the latter.

  • Her three general-field nods were a first for any K-pop idol, proving the genre's U.S. mainstream breakthrough.
