Christina Aguilera Dedicates 'Fighter' Performance to Hillary Clinton: Watch

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.
