Katy Perry lent her voice to Barack Obama‘s presidential campaign on Sunday night when she performed at his latest El Lay fundraiser.
Along with Jon Bon Jovi, Earth, Wind & Fire, Stevie Wonder and Jennifer Hudson, Katy sang her heart out at the Nokia Theatre with hopes of re-electing the Democratic nominee.
She belted out one of her biggest hits, Firework (above) and then covered Al Green‘s Let’s Stay Together to show the POTUS how it’s done!
They totally should have done a duet! Check out her rendition … AFTER THE JUMP!!!
