After Billie Eilish's Grammy snub, Finneas warns fans to avoid online fights. Some fans support him, while others mock his message.

Billie Eilish and her brother and collaborator Finneas paid tribute to Altadena, which was one of the communities devastated in the Los Angeles fires. Performing against a backdrop of the San Gabriel Mountains and Eaton Canyon, the duo delivered a soaring rendition of “Birds of a Feather” at Crypto.com Area.

Billie was joined at the ceremony by her brother and long-time producer Finneas O'Connell, who shared four of her nominations — and subsequent losses. The two also paid moving tribute to Los Angeles following the devastating wildfires when they took to the stage to perform "Birds of a Feather" during the ceremony.
