Stars including Billie Eilish, Pink, Katy Perry, Nirvana and Dr Dre performed at FireAid on Thursday, a benefit concert in Los Angeles to help the area recover from two of the largest fires in its history.

Actor Billy Crystal welcomed the crowd, wearing the clothes he had on when he escaped his home during the wildfires. He had lived in the Palisades for 46 years and spoke from the heart about losing his home. He revealed that Dublin band U2 donated $1 million to relief efforts.
