Audiences tuning into the FireAid benefit concert for Los Angeles on Thursday night (Jan. 30) were surprised with an early treat when pop superstar Billie Eilish made a surprise appearance alongside Billie Joe Armstrong and the rest of Green Day for a stirring opening performance.

Among the headline acts for the show at the Kia Forum is No Doubt, led by Gwen Stefani, which formed in Anaheim in 1986. Before FireAid, the band has only performed once — a reunion at Coachella in April 2024 — since going on hiatus in 2015.

The FireAid benefit concerts are tonight, Jan. 30, at both the Kia Forum and Intuit Dome in Los Angeles. The event will raise funds for relief, rebuilding, and fire-prevention efforts in the wake of devastating blazes across the region claimed dozens of lives and thousands of homes.
