The autism benefit "Night of Too Many Stars" will air Sunday, Oct. 21, and something amazing is going to happen that night. Young Jodi DiPiazza will sing a duet of "Firework" with Katy Perry and bring down the house.

From what I hear this is definitely worth a watch.  The "Night of Too Many Stars," hosted by Jon Stewart, airs Sunday, Oct. 21, on Comedy Central.

Get a few tissues ready for the show-you'll need them when they tell Jodi's story.  Check out the video of the performance below:
