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, Lil Baby, and more are set to participate in FireAid concerts in LA to raise money for those affected by the wildfires.

Green Day had the distinction of being the opening act at the star-studded FireAid benefit concert in Los Angeles tonight. The punk rock trio opted to open with “Last Night on Earth,” the poignant tune from their 2009 album 21st Century Breakdown.
