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.

After Lollapalooza, Rodrigo wrapped her GUTS tour shows when she played Osheaga Festival in Montreal on Aug. 1 and 3. Meanwhile, Weezer will play festivals across the country in August, September and October before heading to South America in November for three shows.
