Demi Lovato and 1/3 of the Jonas Brothers are back together! No, Demi and Joe Jonas aren't dating again, but Demi did do a duet with her longtime friend and 'Camp Rock' costar Nick Jonas onstage during her L.A. concert at the Greek Theatre on July 18!
During the show, Demi called Nick up on stage to join her for duets of her songs "Catch Me" and "Don't Forget."
"Nick is one of my greatest friends that I've ever had," Demi told the crowd. While Demi and Nick sang "Catch Me" together on their Camp Rock tour in 2010, their duet of "Don't Forget" is also special to the pals since it was cowritten by the Jonas Brothers and Nick recently admitted that it's his all-time favorite Demi song.
After the show, Nick took to his Twitter to let the world know how much the night meant to him:
