Lovato and the Jonas brothers performed renditions of “This is Me” and “Wouldn’t Change a Thing”, both of which featured in the 2008 Disney Channel film Camp Rock, which saw Joe and Lovato – who had a real-life, albeit short-lived, romance in 2010 – play love interests on screen.

"We’ve been through so much together," the singer said of her fellow Disney Channel alums. "It was really, really great to spend time with them."

Jonas Brothers recently kicked off their new tour, the ‘Jonas20: Greetings From Your Hometown Tour’, where the trio were reunited with their ‘Camp Rock’ co-star Demi Lovato. The reunion came as a major surprise for fans who could not comprehend that the cast was back together on stage like this.
