May 16 (UPI) -- Christina Aguilera has joined forces with Demi Lovato for a duet about being outspoken titled "Fall in Line."

"I got a mind to show my strength/ And I got a right to speak my mind/ And I'm gonna pay for this," Aguilera and Lovato sing during the chorus. "They're gonna burn me at the stake/But I got a fire in my veins/I wasn't made to fall in line."

"Fall in Line" is set to appear on Aguilera's upcoming eighth studio album, Liberation. The project, which also includes the single "Accelerate" feat. Ty Dolla $ign and 2 Chainz, is scheduled to be released on June 15.
