Joe Jonas and brother Nick Jonas were pictured hugging and singing together as they reunite onstage for the Sunfest Music Festival in West Palm Beach, Florida. It was during Nick’s solo performance on Saturday night when Joe decided to surprise Nick and walk on stage to help sing a song, which was an acoustic Jonas Brothers song ‘Lovebug’. Joe sang along to part of the song before hugging Nick and leaving the stage, as the audience went wild and loved it. Joe’s band DNCE performed the next day at the same festival, and Nick was in the audience watching that show, as well as Joe’s fiance Sophie Turner.
