After seeing his close friend Alex battle cancer, 10-year-old Teagan Stedman decided to do something about it. "Rather than just saying 'I'm sorry...are you okay?' I wanted to do something more," Teagan says. "So I started a charity called Shred Kids' Cancer to help kids who are suffering from the painful disease."

For the second year in a row, Teagan will host a fundraiser called Shredfest featuring kids' bands (including those of Alex, Teagan, and Alex's sister, Emma!) battling it out onstage in front of celeb judges -- all to benefit the Pediatric Cancer Research Foundation and Mattel Children's Hospital UCLA.
