Every Surprise Guest of the Jonas Brothers’ Jonas20 Tour
The kickoff of the Jonas Brothers’ JONAS20: Greetings From Your Hometown Tour was packed with unexpected moments, and fans are excited for more surprises ahead.
This anniversary tour commenced on August 10, 2025, at MetLife Stadium in East Rutherford, New Jersey. Kevin, Joe, and Nick Jonas showcased their deep connection to their home state by introducing several surprise guests throughout the evening, starting with Switchfoot, a band the Jonas Brothers have often cited as an early inspiration.
As the night progressed, the brothers invited Jesse McCartney and Dean Lewis to join them on stage.
The biggest surprise, however, came from a beloved former Disney Channel co-star: Demi Lovato, who joined the Jonas Brothers for a Camp Rock reunion, performing a medley of songs from the 2008 Disney Channel Original Movie and its sequel.
On the second night at Jiffy Lube Live in Bristow, Virginia, on August 12, the surprises continued as Kevin, Nick, and Joe brought out All Time Low to perform.
In an interview with People prior to the tour, Joe hinted that this tour would be “different” from previous ones.
“Fans can expect us to do everything we can to deliver the best show possible every night. We want to have a great time on the road, appreciate the chance to do this after all these years, and bring something unique,” he commented.
