Reflecting on her recent surprise appearance at a Jonas Brothers' concert, the 32-year-old singer called the performance both 'special' and 'healing.'

Lovato admitted she felt "nervous" as she and the JoBros, who reached out "last week" to ask if she would join them on stage, sang "This Is Me" and "Wouldn't Change A Thing," two tracks from the beloved Disney Channel movie that she hasn't performed in years.
