Katy Perry Wants You To Vote — And Look Cute Doing It!

Lady Gaga, Nicki Minaj, Pink, Big Sean and more celebs (even Canadian Justin Bieber!) also tweet about the importance of hitting the polls.

With so many Americans hitting the polls today, it’s no surprise that celebrities are also making their voices heard in the 2012 election. Regardless of who they’re voting for, it’s clear that the overall message these A-listers want everyone to take away is “I voted and I’m proud!” And they hope their fans go out and do the same.

“American Idol” judge Mariah Carey tweeted a photo of herself in line to vote. “The voting continues!” she wrote.

While they’ve reportedly been feuding on the “Idol” set , Nicki Minaj was on the same page as Carey today, tweeting about her fans’ enthusiasm to vote: “Beyond proud of your passion to let your voice be heard. Happy Election Day.”

All this election action is making Lady Gaga very proud — and sleepy. “So great to see everyone so involved today, going to say some political prayers and take a nap. #GodBlessAmerica,” she tweeted.

Some celebrities tried to spread the message to vote by encouraging fans to rock their finest couture when they hit the polls. Mindy Kaling tweeted, “What did you wear when you voted? Electoral sartorial!”

Katy Perry had a similar message for her fans, writing, “Who’s ready to vote tomorrow? I’ve got my outfit laid out! Send me a photo of your outfit when you’re at the polls, and I’ll RT my faves!”

Pink simply wrote, “I VOTED. Feels so good!!!”

Ahead of interviewing the POTUS on his radio show, Ryan Seacrest also placed his vote, tweeting, “Ballot filled out, just gotta drop it off after work. #ivoted #almost.”

Many celebrities were proud to wave their “I Voted” swag once they hit the polls. “Awkward.” star Brett Davern shared, “Just voted! I even have the sticker to prove it! I hope you do too #GoVote.”

Vote how YOU want to vote & what YOU believe in not anybody else.”

While Justin Bieber is finally old enough to vote, there’s a little something holding him back. “im 18…but i cant vote…im Canadian,” he tweeted.
