Fall In Line was believed to be recorded in the autumn of 2017. Lovato slides in on the second verse, adding, "Show some skin, make him want you/ Cuz god forbid you know your own way home/ Ask yourself why it matters/ Who it flatters, you're more than flesh and bone".
"That in this world, you are not beholden, you do not owe them your body and your soul".
Christina teased the release of Fall In Line with baby photos of her and Demi performing as youngsters. Sharing some of the song's lyrics, female empowerment is clearly at the heart of the song.
Aguilera has also announced The LiberationTour dates for the U.S., slated to run from September to November.
Lovato hinted at the collaboration back in February when she told Billdboard, "I did a collaboration with one of my biggest idols".
"I remember being at her concert and singing facing the crowd instead of the stage, knowing that that was exactly what I wanted to do in life".
The two powerhouse vocalists joined forces for a duet called "Fall In Line" for Aguilera's forthcoming album Liberation out June 15. In the recent May 5 issue of the publication, Aguilera confirmed the duet.
