Xtina took over R. Kelly's part on Gaga's ARTPOP track "Do What U Want," which, 1) Sounded incredible, 2) Gave a new lease on life to the song LG's performed on every show known to man, 3) Was lucky timing (for her) given that those 15-year-old allegations of Kelly's predatory sexual behavior are back on the public's mind.
But back to Gaga and Xtina. Not only did they sing together and flawlessly meld their voices, but they held hands, nuzzled and linked arms to toast each other with bubbly. Feud? What feud? Watch the incredible duet above and keep your fingers crossed for an in-studio collabo.
