The Jonas Brothers' 2025 tour kicked off in New Jersey with a surprise guest appearance by Demi Lovato, the band's former Disney co-star.

- Dean Lewis, the Australian pop balladeer of “Be Alright” fame, trotted out mid-set to perform the new “Greetings” tune “Loved You Better,” plinking the piano and unleashing some soaring belts. A chorus from his own multi-billion stream hit would’ve been welcome.

Lovato joined Joe Jonas onstage at MetLife Stadium in East Rutherford, New Jersey, where the pair sang two songs — “This Is Me” and “Wouldn’t Change a Thing” — from their Disney Channel hit movies “Camp Rock” and “Camp Rock 2: The Final Jam,” according to videos posted to social media.
