“Hi. Wow. It’s my first Coachella,” said Williams as she took the stage with Eilish. “Thanks for sharing this with me. This is sick!”
Williams sat on stool in between Eilish and Finneas to treat the audience to an acoustic rendition of “Misery Business,” the 2007 single off of Paramore’s Riot! album.
She also joined in on Eilish’s “Happier Than Ever.”
