Demi Lovato and Joe Jonas' Surprise Camp Rock Duet Is The Reason That We're Singing

Not only did these former lovebirds reunite on stage during Demi and Nick Jonas' tour stop in Washington D.C., but they decided to give the crowd a performance they'd never forget by whipping out their throwback duet "Gotta Find You" from their 2008 Disney film Camp Rock.

The audience understandably went wild as the pair went into song, and Lovato followed up with Mitchie Torres's "This Is Me," with Nick on guitar.
