In the clip, the 31-year-old singer is seen waking from her slumber sporting patriotic pajamas and messy bed hair, complete with popcorn and a lollipop as she declares: 'I've got some great news: This year, you can look like s*** when you vote.'
Katy, who is an avid Hillary Clinton supporter, then walks to her polling station, passing other voters in their nightwear as she explains: 'Yep, I've briefly scanned the Constitution, and nowhere does it say that you can't just roll out of bed and come to the polls in whatever state you woke up in.
'In the name of democracy, any just-out-of-bed look is A-OK.'
She then proceeds to give examples of what is acceptable, including child's onesie, hunk in kid's briefs, that free XL, T-shirt you got from your bank and covered in slime.
She then spices things up a notch as she declares: 'Or, if you're like me, I sleep naked,' before ripping away her pajamas to go nude.
With bars protecting her modesty, Katy grins cheekily at the camera as fellow voters gasp and a man behind her drops to the ground in astonishment.
'Yep, let those babies loose,' she booms, before a pair of police officers strolled over, with one cutting in: 'Alright, ma'am. That's enough of that.'
'No, I read the Constitution and I know I have the right to vote naked, she protests, to which the other arresting officer responds: 'Did you read it, or did you just briefly scan it?'
Leaning out of the window, Katy yells to the camera, before being whisked away: 'Scratch that. Gotta wear clothes. My bad. See you at the polls November 8th.'
