Demi Lovato gave her fans quite the surprise at her Los Angeles show at the Staples Center on Saturday, September 27. Not only did she give a killer performance, but she invited Joe Jonas out on stage with her.
The former couple and now good friends flashed back to their Camp Rock days, and busted out "This Is Me" for her fans. It was pretty much everything, even Joe thought so.
Joe's not the only brother Demi's working with right now, either. She's reportedly recording music with his bro Nick Jonas, too.
Watch Joe and Demi's epic performance below.
