Demi Lovato may have reunited with her Camp Rockcostar and ex, but she only has eyes for her husband. The pop star, 32, joined Joe Jonas, 35, on stage for a duet of "Gotta Find You" at the Jonas Brothers' Sunday,

Demi Lovato found it "really healing" to perform with the Jonas Brothers over the weekend. The 32-year-old singer-and-actress made a surprise appearance at her Camp Rock co-stars' show in New Jersey on Sunday (Aug 10) and not only was it "so nice" to be back on stage with the trio after receiving a call from ex-boyfriend Joe Jonas,

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.
