Some of music's top young stars have recorded a series of public service advertisements (PSAs) that will be used to promote Walk Now for Autism events across the country this year.

“American Idol” winner Jordin Sparks and top selling bands Fall Out Boy and the Jonas Brothers recorded the ads during the Z100 Jingle Ball concert in New York City in December. “Gossip Girl” star Chace Crawford also contributed his talents to the project.

The ads state that another child is diagnosed with autism every twenty minutes and encourage viewers to take part in Walk Now for Autism events in their community.
