The band — consisting of brothers Joe, Nick and Kevin Jonas — kicked off their 20th anniversary tour on Sunday at MetLife Stadium in their home state of New Jersey. But to make it more special, they surprised their fans with some special guests throughout the show, including Demi Lovato .

Joe, Nick and Kevin kicked off their 20th anniversary tour with Sunday night’s show at MetLife, one of the largest venues they’ve ever played together. An NJ Transit line was temporarily renamed the “Jonas Brothers Hometown Express” to help fans get to the Jersey natives’ show.

After wrapping their performance of “This Is Me,” the DNCE frontman told the screaming crowd that he and Lovato hadn’t performed the track for “almost 10 years.”
