SJP isn't the only actor playing the role of Good Citizen this weekend (scroll down to see what we we're talking about). TV-star hotties like Desperate Housewives' Shawn Pyfrom and Gossip Girl's Penn Badgley are in the Midwest urging the good people of Ohio to vote early!

Why? For one thing, you can bet the polls are going to be a mad house in this swing state on Tuesday. It's a fact: More people than ever will be casting their vote before rather than on Election Day -- 30 to 35 percent of the total electorate, according to the New York Times, compared to 22 percent in 2004. Go here to find out if your state offers the opp to vote early.

This election has brought celebs together like none before. What's next? Madonna doing door-to-door canvassing? We can only wait and see. Four days to go, people!

Do Something this weekend to help get out the vote -- on Tuesday or before. Check out our voting action guides.
