Jonas Brothers Bring Out Demi Lovato For Unforgettable MetLife Stadium Performance: Watch

What year is it again? The Jonas Brothers brought out Demi Lovato for an unexpected collaboration.

On Sunday, August 10, the trio performed the first concert of their 20th anniversary Greetings From Your Hometown Tour. After not being seen in the public eye together in years, Demi and the brothers reunited for a special performance at MetLife Stadium in New Jersey.

Kevin, Joe, and Nick performed the “Gotta Find You” and “This Is Me” mashup from the original Disney Channel Camp Rock film. But that’s not all. The four-piece then went into the Joe-Demi duet from the second film, “Wouldn’t Change a Thing.” Despite it being seventeen years since the first film premiered, the artists sounded even better than the original recordings.

Jonas Brothers, Demi Lovato and Camp Rock 3 Rumors

Camp Rock 3 rumors have been circulating for the last several months. Rumors are swirling that the third installment of the franchise is officially in development, thanks to a major tease from original cast members. At the “Bop to the Top Tour” concert at Anaheim’s House of Blues, actors Matthew “Mdot” Finley (Luke Williams), Anna Maria Perez de Tagle (Ella Pador), and Roshon Fegan (Sander Loyer) sent fans into a frenzy. Finley asked the crowd, “Are y’all ready for Camp Rock 3? I’m not sure if y’all heard, but, Camp Rock 3 is on!”—a moment that instantly went viral online.

Earlier this year, Production Weekly released an early synopsis detailing a modern twist: “When a popular band needs to find a new opening act, they launch a contest to discover the next big musical talent.”

Original cast member Alyson Stoner (Caitlyn Geller) revealed she’s not yet been contacted about Camp Rock 3, noting she often hears franchise news online. Meanwhile, Joe Jonas, who played Shane Gray, offered a playful confirmation during a recent interview—when asked if he would return, he quipped, “How do you know that I’m not… I can neither confirm nor deny.”
