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

Kevin, Joe and Nick Jonas, and Lovato performed a "Gotta Find You" and "This Is Me" mashup from the 2008 Disney Channel musical "Camp Rock."

Lovato and Joe Jonas later performed their duet "Wouldn't Change a Thing," from the sequel "Camp Rock 2: The Final Jam."

The Jonas20: Greetings from Your Hometown Tour got underway Sunday in the band's home state for the first of 52 concerts over three months across the U.S. and Canada.

NJ Transit operated special "Jonas Brothers Hometown Express" trains to shuttle concertgoers between Secaucus Junction and the Meadowlands Sports Complex for the show.
