Must Watch! Katy Perry's Tear-Jerker Duet

Comedy Central
Is it possible to watch Katy Perry and young musician Jodi DiPiazza sing Firework without crying? Maybe, but we don't think so.
During Comedy Central's Night of Too Many Stars: America Comes Together for Autism Programs, airing Sunday night, the audience heard DiPiazza's story about living with autism and using music as an outlet to express herself. There was even a point in the young girl's life where it was thought she wouldn't speak, but nonetheless, the walking miracle shared the stage with Perry for a heart-tugging duet.
Grab the tissues and get ready for the waterworks when the ladies perform about 3:30 minutes into the piece. The Night of Too Many Stars is a charity event to raises funds in support of autism schools, programs and services all over the country.
