During last night’s grand finale of The Voice, Lady Gaga and Christina Aguilera officially ended their alleged feud by going on stage together to sing a duet of Gaga's “Do What U Want” single.



Dressed up in matching iridescent getups, the pair almost seemed to be competing on who could wail the loudest without accidentally making everyone in the audience go deaf. At one point, Aguilera even caressed Gaga's head before they chug champagne and throw their glasses to the floor.
