Jimmy Fallon surprised Jonas Brothers fans when he appeared as a special guest for their concert at New York’s Yankee Stadium on Saturday night (12 August).
Footage shared by @caliiinoel on X, formerly Twitter, shows the Tonight Show host joining the band to perform The Killers’ song “Mr. Brightside.”
“How would you all like to be in the world's biggest karaoke party for two minutes?” Fallon, 48, asked the 60,000 fans in the stadium before launching into his rendition of the 2004 hit.
