Hopefully Katy Perry wont have another crazy Friday night shell be performing at her third Obama rally on Saturday.President Obama will join her at the Milwaukee, Wisconsin event.

After an Oct. 7 rally in Los Angeles, the singer tweeted, I sang for President @BarackObama last night because I believe in Equal Rights #ForAll #Vote . Her Ballot Dress during a recent Las Vegas rally/performance pictured above made headlines, alongside her encouragement of early voting.

Perry is far from the only celebrity stumping for a presidential candidate in the final days of the campaign. Bruce Springsteen and Jay-Z will also be making last-minute swing-state get out the voteappearances alongside President Obama. And of course we cant forget about Meat Loaf and Lindsay Lohan publicly backing Mitt Romney although, alas, ! no Lohan events have been announced.

The people have the power, Perry declared, before launching into Firework at last weeks Las Vegas rally. Check it out below:
