A cavalcade of enormous rock and pop stars, old and new, will perform at an enormous benefit concert in Los Angeles, and streamed around the world.

The members of No Doubt -- Gwen Stefani, Tom Dumont, Tony Kanal and Adrian Young -- reunited at FireAid Thursday night and sang some of their biggest hits, including "Just a Girl," "Spiderwebs" and "Don't Speak."

Billie Eilish sang with Green Day and Stevie Nicks thanked the firefighters who saved her home at two star-studded concerts on Thursday to raise money for wildfire relief in Los Angeles.
