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 .

According to data by FlixPatrol, Camp Rock currently ranks at number 8 in the Top 10 Overall most-watched things on Disney+ today, marking a shocking comeback for the film following Lovato and the Jonas Brothers’ performance. The movie sits just below Ice Age at number 7, and above Marvel’s Eyes of Wakanda and Captain America: Brave New World.

The pair sang "This Is Me" and "Wouldn't Change a Thing," 17 years after the Disney Channel original movie was released.
