Dave Grohl made a surprise appearance last night, December 15, on stage with Billie Eilish at the Kia Forum in Los Angeles. Grohl took the stage with an acoustic guitar and thanked Eilish for wearing her Taylor Hawkins shirt during her performance at the GRAMMYs earlier this year. The duo then launched into an emotional cover of Foo Fighters' "My Hero" which you can check out above.
"Earlier this year, all of the Foo Fighters and our families gathered together at my house to watch the GRAMMYs," said Grohl. "When Billie came out for her performance in the Taylor Hawkins t-shirt, the room was filled with real tears of love and gratitude. From our families who are here tonight – the Hawkins family and everyone – we'd like to thank you for that. Let's sing it for Taylor."
