Old school met grade school on Saturday at the Coachella Music & Arts Festival in Indio, California.

No Doubt made its first headlining appearance since 2015 at the festival, joined by Olivia Rodrigo, who was 10-years-old when the band last performed.

Rodrigo joined Gwen Stefani, Tony Kanal, Tom Dumont, and Adrian Young on stage during the band’s 2000 hit, Bathwater, released nearly three years before Rodrigo was born.

The No Doubt set included Sunday Morning, Don’t Speak and Spiderwebs, among others. Old video footage of the band’s heyday played on the video screens throughout the set.

Stefani had a bit of gender-bending fun with the crowd, asking the boys to sing the hook to I’m Just a Girl in a call-and-response moment,

No Doubt will headline Coachella again during the festival’s second weekend.
