Perry urges fans to vote for Obama

Katy Perry made it very clear who gets her vote as she performed at a rally concert for US president Barack Obama.

The 'Firework' singer wore her heart on her sleeve with a latex dress designed to look like a ballot paper, with the box filled next to Obama’s name filled in to represent her vote, while his opposition Mitt Romney’s box was left empty.

The 28-year-old singer wore the dress to sing at the America Forward Grassroots rally in Las Vegas, encouraging Americans to “vote early”, ahead of the upcoming presidential elections in November.
