Christina Aguilera Is Channeling Jessica Rabbit With Her New Hair Color

Ever-changing Christina Aguilera has left behind her platinum blond and lavender hair, and her transformation to a readhead is so hot!

The singer and The Voice judge showed off her bombshell new hair on Instagram, giving us serious Jessica Rabbit vibes with her soft Old Hollywood waves right before hitting the stage at a concert in support of presidential candidate Hillary Clinton.

It's been a while since Christina, whose dad is from Ecuador, sported a fiery look — you might remember her red streaks from her "Come on Over (All I Want Is You)" days. Scroll ahead for more photos of her new hair shade, then watch a young Christina slay Whitney Houston's "I Have Nothing."
