Demi Lovato wouldn't change a thing about how her epic reunion with the Jonas Brothers came to be. Two days after Lovato, 32, surprised fans by performing with the band on the opening night of their JONAS20: Greetings From Your Hometown Tour at MetLife Stadium in East Rutherford, New Jersey, the Disney Channel alum opened up about the experience on the "Chicks in the Office" podcast on Tuesday, August 12. Lovato told hosts Maria Ciuffo and Francesca Mariano how Joe Jonas, her ex-boyfriend, asked her to appear at the show.
