The Jonas Brothers transported fans back to the 2000s with special appearances from Jesse McCartney and their Camp Rock co-star Demi Lovato during their JONAS20 tour opener at MetLife Stadium in their home state of New Jersey on Sunday (August 10).
Joe, who played Shane Gray in the 2008 blockbuster, serenaded the crowd with a few bars from "Gotta Find You," before Lovato, who played Mitchie Torres, stepped on stage and stole the show with "This is Me." The duo, who dated in real life (per People) and played love interests in the beloved Disney film, also sang "Wouldn't Change A Thing," as if 17 years hadn't passed since the end of final jam.
During the show, Joe and Demi let the audience know that this was the first time they had performed the duet in over 10 years!
Lovato shared footage from the performance on Instagram, thanking the Jonas Brothers for allowing her to perform with them.
The "Sucker" standouts also surprised fans present at the first show of their tour with another special guest!
The band welcomed Jessie McCartney on stage to sing his 2004 hit, "Beautiful Soul," and the crowd went absolutely wild!
But that's not all!
The Jonas Brothers pulled out all the stops for their tour opener and even brought out the remaining members of their immediate family, their parents, Kevin Jonas Sr. and Denise Jonas, their younger brother Frankie, Kevin's wife, Danielle Jonas, and the pair's children, Alena, 11, and Valentina, 8, to help them sing "When You Look Me in the Eyes."
The band's next show, featuring Marshmello and The All-American Rejects, will take place on Tuesday, August 12!
