Katy Perry and Jodi DiPiazza, who has autism, bring down the house at the "Night of Too Many Stars"

Jodi DiPiazza was lucky enough to get into one of the few schools available to help children with autism to reach their potential.

Loud temper tantrums often flared up during those pre-kindergarten years, but during many hours of therapy, Jodi found a talent that truly grounded her -- music.

"We were afraid she would never speak. Never dreaming she would sing, or even be able to understand," said her father in the video below. "I've taken off the idea that there is some limit on her, as she continually proves that that's not true."

During the October fundraising gala for autism, Night Of Too Many Stars hosted by Jon Stewart, Jodi got the chance to play and sing with her favorite singer, Katy Perry.

Stewart introduced the pair saying, "People with Autism shouldn't be written off. They deserve, like everyone, the chance to reach their potential."

The annual star-studded night of comedy and entertainment raises money for New York Collaborates for Autism(NYCA) to support and create autism programs, schools, and services all over the country. Programs covering everything from the intensive education kids with autism need at a young age to social training for adults who want to contribute in the workplace. They've even created a "Teach the Teachers" program that helps train more teachers to work in the public school systems, for the many kids with autism who can't get into the few quality schools that can help them.
