Fully immersing themselves in Tuesday's political festivities, the stars took to the polling booths and Twitter to sound off on the Presidential election.
Many of the celebs opted for a general encouraging tweet to get to the polls with some even offering incentives to do your civic duty, as Darren Criss offered a signed Rock the Vote T-shirt while Katy Perry offered to retweet her favorite fan election day outfits.
All three Kardashian sisters encouraged their millions of Twitter fans to follow their lead and vote, while Miley Cyrus, Mandy Moore, Heidi Klum and Halle Berry were among the famous faces spotted casting their ballots.
Meanwhile, Latino stars made a big push for President Obama this year, with Ricky Martin tweeting a photo of himself at a Florida campaign rally for Barack, George Lopez promising to deliver Colorado for Obama, and Eva Longoria gushing over fellow Obama supporter Will Ferrell's hilarious new voting video.
Encouraging fellow women to support President Obama were Rashida Jones, who called for ladies to vote in "our election" and Mariah Carey, who joined the First Lady Michelle Obama in North Carolina.
Aside from the race to the White House, a controversial California Proposition regarding genetically engineered or genetically modified food labeling earned the attention of Charlie Sheen and Nina Dobrev, who will vote "yes" on the measure.
