Singer Christina Aguilera announced her third single off of her new album Liberation tomorrow in collaboration with Demi Lovato.
The start tweeted childhood pictures of Demi and her as she wrote, "Little girls
'cause no one told me
But you deserve to know
That in this world
You are not beholden
You do not owe them
Your body and your soul
#FallInLine. Tomorrow, 8am EST."
Their fans went crazy as when of them wrote,"two female idols = woman empowering anthem ???? #FallInLine."
Another fan tweeted,"Christina Aguilera and Demi Lovato in the studio together."
"I CAN'T WAIT TO HEAR FALL IN LINE TOMORROW!!!!!! YAAAAS QUEENS!!!!!! @xtina @ddlovato #FallInLine,"wrote a fan.
The photos serve as a reminder that Aguilera and Lovato have been in the game for a while, with both of them getting their start as child performers in talent shows and television programs.
