Portrait of Jonas Brothers & Demi Lovato Brings Nostalgia for CAMP ROCK on 20th Anniversary Tour, Reunion of Exes

The moment got even more exciting when Joe and Demi, who also briefly dated in 2010, sang two iconic songs from the film, This Is Me and Wouldn't Change a Thing.

After This Is Me, Joe slipped in a snippet of the lyrics to Gotta Find You and admitted that they hadn't performed that song together in almost 10 years. Demi chimed in, "It feels like it's been even longer."

Kevin and Nick, who played Jason and Nate in the film, also reminisced. Nick even shared stories about the audition process back then.

"At first, they only wanted Joe, but somehow, our dad managed to get me and Kevin involved as well. Now, it's time for us to walk down memory lane to celebrate a little film called Camp Rock," said Nick.

Demi's husband, Jordan "Jutes" Lutes, also shared this historic reunion moment on social media. He uploaded a video of Demi taking the stage to a warm welcome, writing, "Couldn’t be prouder… I love you so much, baby," complete with a tag to Demi's account.

Joe and Demi were also seen sharing the fun on Instagram. They lip-synced to the song Wouldn't Change a Thing.

They even reenacted the iconic moment of Debby Ryan on Disney Channel. Who's happy to see them reunite?
