Watch Billie Eilish Make Surprise Appearance With Paramore In Los Angeles

Paramore played the first show of a two-night run at The Forum near Los Angeles on Wednesday night. The encore featured a pair of special guests as the band was first joined by Billie Eilish and then the members of MUNA who also came out during the finale.

“Please welcome my friend Billie Eilish,” said Paramore lead singer Hayley Williams before Eilish emerged shortly after Paramore kicked off the encore with their 2009 hit “All I Wanted.” Eilish sang one of the verses and harmonized with Williams.

“Paramore you guys, what the fuck!” shouted an exuberant Eilish before leaving the stage. Watch the surprise sit-in via the audience-shot video below:

Wednesday’s encore continued with another favorite, “Still Into You” off their 2013 self-titled album. The final song of the night was “This Is Why,” the title track to their recently released album. Paramore welcomed the members of Muna onstage to dance along to “This Is Why.”

During their main set, Paramore brought up a member of the audience to help sing “Misery Business.” Paramore returns to The Forum tonight with Foals and The Linda Lindas set to open.
