Christina Aguilera has been one of Hillary Clinton's loudest and most famous supporters for years, and the singer used her voice to inspire voters one last time this election season.

Xtina released her performance of an acoustic version of her anthem "Fighter," dedicated to the Democratic nominee. She performed it at a rally for Clinton on Sunday (Nov. 6). We've heard Aguilera perform this song countless times, but there seemed be an additional fierceness and fervor in her voice this time.

At the end of the rendition, Christina addressed the crowd. "Anybody you can reach out to, knock on doors, get 'em to vote," she said. "At this point, every bit counts. Please, make it happen. Everybody that you work with, that know you, email, tweet, it all counts. I'll be doing the same."

Make sure you follow that good advice, get the word out, and be sure you yourself vote—as long as you get there before your polling station closes, you can still vote. Here's a handy way to find your polling station.
