The one thing that sets Katy Perry apart from all the other huge Pop icons out there is that she truly cares about her fans, and wants them to be part of her creative process. She even had fans design her official “Katy Perry: Part of Me 3D” poster, and many of her songs are written to inspire them.

If you have seen her concert film, you know exactly who Katy is. She is a regular girl with an amazing gift, and now that she’s made it, she wants to make the lives of the less fortunate much better.

On Sunday, October 21 at 7PM CST, the “Night of Too Many Stars: America Comes Together For Autism Programs” premieres on Comedy Central. In this special, Katy Perry sings her hit “Firework” as a duet with an autistic 11-year old named Jodi DiPiazza at the Beacon Theater in New York. This performance is quite the tear-jerker.

The program be streaming live via Ustream and will be simulcast on comedycentral.com. The special hosted by Jon Stewart features live music performances, comedy sketches and shorts from all-star celebs while raising money for autism programs, schools, and services across the United States. Click here to find out how you can help the cause.
