It's Election Day, and the stars are heading to the polls.

As Vice President Kamala Harris and former President Donald Trump face off in the U.S. presidential election on Tuesday, celebrities are showing off their red, white and blue "I Voted" stickers and sharing their patriotic musings.

Pop star Pink shared a selfie on Instagram Monday after casting her vote. The Grammy-winning singer revealed she voted for Harris and her vice-presidential running mate, Minnesota Governor Tim Walz.

"We have to use our voices if we want a world that reflects who we are," Pink wrote. "This isn't the time to sit back and watch; don't leave it up to anyone else to make the decisions that impact your life."

The "Dear Mr. President" singer encouraged her followers that their "vote matters now more than ever."

"Vote for democracy, vote for love and vote for respect," Pink continued. "Vote for your family, your loved ones and your community. Freedom of the press, reproductive freedom, the right to vote, the right to read books. The right to go to school and get an education separate from religion. Vote for the future. Vote for decency."

Here's what other stars are saying about Election Day.

Reese Witherspoon champions women's rights with Harris vote

Reese Witherspoon headed to the polls early, sharing a post-vote selfie on Instagram Friday. "The Morning Show" star said she voted for Harris because of the vice president’s stance on reproductive rights.

"Top of my mind, as I considered all candidates, is protecting women's rights to medical privacy and reproductive choice," Witherspoon wrote. "This is a critical time in our shared history to vote for the candidate that represents the future we want to see. That's why I voted for Kamala Harris for President.

"For my daughter and for the millions of hard-working American women who value our freedoms. I want to protect democracy at all costs. I love my country and no matter what happens in this election, I'm here to move our great nation forward in a unified way."

Queen Latifah shares playful Election Day video, slams Donald Trump

Queen Latifah got into the voting spirit with a playful "get ready with me" video posted to Instagram Tuesday. In the clip, the actress and rapper can be seen getting dolled up for Election Day in a black, pinstripe shirt and a white turtleneck top that reads "Vote" along the collar.

Latifah offered a more serious tone in the post's caption, slamming Republican nominee Trump.

"On one hand, we have HIM, a felon, a comfortable liar, an impeached president, a misogynist, and a non-leader who doesn't care about anyone, but the top 1%...which excludes over 300M Americans," Latifah wrote.

In contrast, the "Living Single" star enthusiastically endorsed Harris' presidential bid.

"And on the other hand, we have HER, Kamala Harris, a proven leader, a knowledgeable, lifelong civil servant for the people, and a compassionate human being with the strength to lead and navigate our complex government who puts the needs of all Americans first….a candidate with a detailed plan to take us forward."

And I just wanted to make this video really quick to say: Please stay in the line," she said in a video posted on X, formerly Twitter, as well as her Instagram Story. "Long lines are really frustrating and annoying, and I know they're not fun, but we need your voice and vote for your future.

"Today not only did I vote for access to health care, for reproductive freedom, for equal rights, for safe schools, and for a fair economy, but also for SANITY and HUMAN DECENCY," Aniston wrote. "We are so lucky we get to VOTE and this election is in our hands!"

While Aniston recognizes "we don't agree on everything, and that is the beauty of this country," she added, "Aren't you tired of this negativity towards each other? The intimidation and constant threats to those who do not think the same as the other?"

"Let's please end this era of fear, chaos and the attacks on our democracy - and vote for someone who will unite us and not continue to threaten to divide us 🙏🏼" Aniston concluded.
