Though Kourtney's sister, Kim, has stayed off social media for the most part since her robbery last month, the Selfish author publicly endorsed Clinton on her blog in September.

"I found that without a doubt, I stand with Hillary. I'm with her. I believe Hillary will best represent our country and is the most qualified for the job," Kim revealed. "This year, I'm not just voting for myself, but also for my children, and I took that into careful consideration when I made my decision."

Kourtney isn't the only celeb heading to the polls. Other stars like Taylor Swift, Lady Gaga and Miley Cyrus have cast their ballots and encouraged others to do the same.
