Since the rumors of a duet between Christina Aguilera and Demi Lovato leaked months ago, it's been the most anticipated song of Xtina's new era — sorry, "Accelerate." And finally "Fall in Line" is here and...we're shaking. "Fall in Line" is an anthem of femme empowerment where these two pop divas seamlessly blend their huge voices and our wigs have shot off into the stratosphere.
Listen to "Fall in Line" below.
You won't need to wait long to hear the song live: Xtina and Demi will perform it this weekend at the Billboard Music Awards.
