Katy Perry showed off her political persuasions - and continued penchant for PVC - as she performed onstage at an Obama campaign rally in Las Vegas.

The 28-year-old singer, known for her risqué outfit choices, hit the stage at the 'America Forward' event at Doolittle Park in Sin City wearing a long-sleeved latex mini-dress, which resembled a ballot slip with the words 'President of the United States' emblazoned across her chest and a coloured-in black mark next to Barack Obama's name.

She added a pop of colour to the ensemble with red Mary Janes and wore her hair in loosely pinned-up waves as she performed her hit songs Firework and Teenage Dream and encouraged the 13,000 audience members at the rally to 'vote early.'

She told the crowd: 'Don't wait. Go tomorrow. How many of you are 18 here? It's going to be your first time, right?'

'I've got to know Katy and she's a wonderful young lady,' Barack Obama told the crowd. 'And I can tell that part of it is because of her outstanding grandma Anne, a 50-year resident of Nevada.

'The only thing I have to say is Anne got some lipstick on me when she kissed me. Fortunately somebody wiped it off before Michelle saw it.'

Katy Perry lent her vocal talents to Obama's campaign earlier this month, when she performed before a star-studded crowd at his '30 Days to Victory' re-election concert.
