Olivia Rodrigo and Robert Smith Perform Duet at Primavera

In a surprise performance at the Primavera Sound festival in Barcelona on Saturday, pop star Olivia Rodrigo debuted her first-ever duet, a new song featuring Robert Smith of the legendary British band The Cure. The collaboration, titled "What's Wrong With Me," was unveiled during a set that was announced only hours before Rodrigo took the stage.

Introducing the track to the crowd, Rodrigo said the song was special primarily because it marks the first time she has included a featured artist on one of her recordings. After singing the first verse and chorus, she welcomed Smith to the stage, where he performed the second verse wearing his signature all-black attire and makeup. The two artists then harmonized on the chorus, which includes the lyrics, "My head is spinning and my stomach is sick / Say I'm in love, so it's hard to admit / I can't eat, I can't sleep / I think you're what's wrong with me."

Rodrigo expressed her disbelief after the performance, telling the audience she felt like she was going to cry and that she could not believe the duet was a real event and not a figment of her imagination. The performance was streamed live.
