The Jonas Brothers opened their 20th-anniversary “JONAS20: Greetings From Your Hometown” tour at MetLife Stadium in East Rutherford, New Jersey, on 10 Aug 2025 with an unannounced appearance by longtime collaborator Demi Lovato. Lovato joined Joe, Nick and Kevin Jonas to perform the Camp Rock staples “This Is Me” and “Wouldn’t Change a Thing,” marking the first time the songs had been sung live together in about a decade. The reunion came 17 years after Disney Channel released the original Camp Rock movie that helped launch both acts’ careers, and roughly 15 years after its sequel. Joe Jonas introduced Lovato onstage moments after singing his solo number “Gotta Find You,” telling the crowd they had not played the duet for “almost ten years.” Lovato responded that it “might have been longer,” underscoring the nostalgia-driven tone of the night. Additional cameos included singer-songwriter Jesse McCartney, who delivered his 2004 hit “Beautiful Soul,” and the brothers’ younger sibling Franklin Jonas. The tour backs the group’s newly released seventh studio album, “Greetings From Your Hometown,” and is scheduled to cover 52 dates across the United States and Canada before concluding on 14 Nov in Uncasville, Connecticut.
