Add Jessica Alba to the list of celebs urging young people to vote this election season.
The starlet will appear in Declare Yourself's new "Only You Can Silence Yourself" PSA campaign, in which celebs and real people are shown crying and with their mouths forced shut.
In 2004, the campaign was launched with a photo of Christina Aguilera in which her lips appeared tied together with leather string, while screws and bolts were used on Mean Girls actor Jonathan Bennett.
"Only you can silence yourself," reads the tagline for the campaign. "Make them hear you. Register to vote now."
