Los Angeles: Singer Katy Perry says performing her single "Firework" at a charity fundraiser with autistic fan Jodi DePiazza, has been her career`s highlight.

The 28-year-old singer shared the stage with DePiazza, 11, at a taping of Comedy Central`s show "Night of Too Many Stars" last year. Her fan had played the piano and sang along with Perry, reports

"`Firework` is the most important song I`ve written. Performing it with an autistic girl accompanying her on piano and vocal harmony at a fundraiser was the most important performance of my career," Perry said at the ASCAP I Create Music Expo.
