The 'Firework' star pledged her allegiance to the American leader with the flamboyant attire.
Katy Perry was pictured on stage at yesterday's (24th October) Barack Obama Las Vegas rally wearing a latex dress made out of a giant ballot voting slip.
The 'I Kissed A Girl' singer took to the stage in the eye-catching white outfit to perform a cover of Al Green's 'Let's Stay Together' before giving an outing to some of her biggest songs including 'Teenage Dream'.
The American star was also heard encouraging some of the younger members of the audience to "vote early".
She declared: "Don't wait. Go tomorrow. How many of you are 18 here? It's going to be your first time, right?"
The backing screens featured shots of the current US President and images taken from some of his other rallies.
Bruce Springsteen had also performed at the rally, where he could be heard giving his best impression of the President as he spoke about their friendship to the crowd.
Katy's recent performance comes just weeks after she also made an appearance at a fundraiser in Los Angeles which also featured stars such as Stevie Wonder and Bon Jovi.
Obama has received huge support from the music world including the likes of Lady Gaga as well as Beyonce and Jay-Z – who helped raise $4 million for his re-election campaign.
