In addition to their musical reunion, Lovato and Jonas found time to collaborate on a couple of TikToks that were seemingly filmed backstage, including one in which they lip-synced to fellow Disney star Debby Ryan’s infamous speech about sitting down with the president of the Disney Channel and saying she wanted to make history.

Lovato joked at Sunday's (Aug. 10) show at MetLife Stadium in New Jersey that it "might have been" more than a decade since she and Joe sang together.
