What’s with these homies dissin’ my girl? This is a question Rivers Cuomo has wondered many times, and now Olivia Rodrigo is wondering as well. Last night the pop star — who also recently brought out David Byrne for Talking Heads’ “Burning Down The House” at Gov Ball and Robert Smith for some Cure hits at Glastonbury — was joined by Weezer at Lollapalooza for “Buddy Holly” and “Say It Ain’t So.

The pop vocalist also treated the Lolla crowd to her solo hits "Driver's License," "Traitor," "Love Is Embarrassing" and more. The festival continues into Sunday (August 3) with more headlining sets from Rüfüs Du Sol, TWICE, Sabrina Carpenter and A$AP Rocky.
