When the biggest names in music come together for the 2018 Billboard Music Awards on May 20, two of pop's powerhouses will join forces for what might just be the most dynamic performance of the night: Christina Aguilera and Demi Lovato.
The pop divas will debut their highly anticipated collaboration "Fall In Line" on the show, as they each announced on their social media accounts Tuesday morning (May 8). Lovato and Aguilera have been teasing a duet for quite some time, with the track finally coming to fruition on Aguilera's forthcoming album, Liberation (due June 15), which the Billboard cover star announced last week.
