The 'Firework' singer sang an Al Green cover as she confirmed her support for this year's presidential election.
Katy Perry showed her support for US president Barack Obama on his re-election campaign by hosting and performing at a fundraising concert over the weekend.
The 'Part Of Me' star joined the likes of Jennifer Hudson, Stevie Wonder and Jon Bon Jovi at the Nokia Theatre in Los Angeles on Sunday night (7th October) in front of a large crowd of Obama supports, and urged fans to vote for "equal rights for all".
"Today I am so honoured to play for the President!" Katy tweeted ahead of the live show, before adding on Monday: "I sang for President Barack Obama last night because I believe in Equal Rights For All."
Katy wore a white dress emblazoned with the image of the US' national bird, the American bald eagle, as well as wearing a belt in the shape of the White House.

The 'Firework' singer also tweeted fans to show off her patriotic themed fingernails, painted with stars, stripes and pictures of Barack Obama's face.

Katy also performed her song 'Firework' as well as a cover of Al Green's 'Let's Stay Together' at the concert, while wrapped in an American flag.
Obama himself appeared towards the end of the show, where he was quoted making a joke about his widely criticised debate appearance in Denver last week opposite Republican candidate Mitt Romney.
Katy Perry has been working hard on music for her third studio album over the summer, and was recently reported to have split from much rumoured boyfriend John Mayer.
