"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 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."
