If you've already listened to and loved Christina Aguilera's recent collaboration with Demi Lovato, "Fall in Line," then please trust us when we say that their live rendition at the Billboard Music Awards on Sunday night will floor you. The two divas and run queens hit the stage with plenty of sultry energy as they belted out their duet in a sci-fi-tinged, Matrix-esque performance. "Fall in Line" is off of Aguilera's forthcoming album, Liberation, which drops June 15 and will be her first since 2012's Lotus. Feel free to watch it over and over again above, and then check out the event's full list of winners.
