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.

Alyson Stoner and Demi Lovato have made up, but decades earlier Stoner describes a tumultuous "Camp Rock" tour because of Lovato's substance abuse.

"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."
