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."

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