Lady Gaga and Bruno Mars performed a hauntingly beautiful cover of "California Dreamin'" at the 2025 Grammy Awards

Lady Gaga and Bruno Mars took a nostalgic trip to pay tribute to Los Angeles. The pair performed a cover of The Mamas & The Papas’ ‘California Dreamin’ as they took the stage at the Crypto.com Arena for a special duet at the 67th Grammy Awards in honor of those impacted by the recent wildfires.

Just days before the Grammys, rumors began to swirl that Lady Gaga and Bruno Mars were tapped to perform at the ceremony last minute. But though the duo’s last collaboration, “Die with a Smile,” became a global smash hit — rising to the top spot on the Billboard Hot 100 last month — it seemed like its lyrical content might be out of place for a telecast dedicated to fundraising for Los Angeles wildfire relief.
