After performing an unreleased song about hope amid chaos at the Los Angeles benefit concert FireAid Thursday, Lady Gaga will perform a tribute to those affected by the fires alongside Bruno Mars at the 2025 Grammys on Sunday.

After almost six hours of FireAid, Lady Gaga ended the historic Los Angeles event by debuting a new song co-written with her fiance Michael Polansky, an upbeat number that she said was “just for tonight.”
