Olivia Rodrigo performed as part of Los Angeles’ FireAid Benefit Concert to fundraise for victims of the wildfires.

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."

Once it came time to perform, however, Rodrigo channeled her on-stage alter-ego—who has a known affinity for hot pants and sparkle. She went from red-white-and-blue to all-black, wearing an off-the-shoulder lace top from Rabanne and matching sequin undies. Together, the two glitzy pieces formed a dazzling bodysuit moment.

Abrams, meanwhile, wore a white knit halterneck gown that featured a delicate scalloped neckline and floral filet lace, similar to the slightly sheer crochet styles that Birkin often wore in the late ‘60s. Abrams rounded out her look with stud earrings and black leather flats.
