NEW YORK (AP) - How do you get kids to vote? Just say no. Leonardo DiCaprio, Halle Berry, Jennifer Aniston, Tobey Maguire, Eva Longoria Parker and other stars are using reverse psychology to get young people into voting booths on Election Day.

In a new public service announcement that hit YouTube and other online outlets Wednesday, DiCaprio says: "Please - just don't vote." Others echo his plea: "Don't vote." But the stars soon twist the message: Voting is a civic duty and the only way to effect change.

"I mean, seriously, ... after this whole video - if you're not gonna vote, I don't even know what to say. ... You know you have to vote," says DiCaprio, who produced the PSA.

Also appearing: Ellen DeGeneres, Forest Whitaker, Dustin Hoffman, Demi Moore, Sarah Silverman, Jonah Hill, Ashton Kutcher, Courteney Cox, Laura Linney, Natalie Portman, Jamie Foxx, Usher, Kyra Sedgwick and will.i.am.
