Billie Eilish surprised the Coachella crowd last Saturday night through performing songs together with Hayley Williams from Paramore.

Eilish introduced Williams when spectators noticed the two stools placed on stage. “Oh, look! An empty seat. Who’s that for?” The “Bad Guy” asked the audience, which she said after, “Everybody, can we please welcome my friend Hayley Williams!”, according to Variety.

On the publication’s Twitter account, a video was posted showing Williams and Eilish dueting to Paramore’s hit 2007 pop-rock song, “Misery Business.”

A clip was shown prior to the performance where Williams expressed her anticipation for making a Coachella appearance in which she revealed, “This is my first Coachella, whoa.”

“Thanks for sharing this with me. This is sick!” Williams told Eilish and the crowd.

The two performed an acoustic version of “Misery Business” with Eilish’s brother Finneas, played his guitar. 

Fans couldn’t contain their excitement as well and took it to the social media.

“hayley williams and billie eilish went from fangirling over each other on social media for years to singing together at coachella,” mar_9 wrote with a snippet post.
