You've probably heard the version of Lady Gaga's latest single, "Do What U Want," featuring R. Kelly. She performed it on a handful of award shows and it's also played pretty regularly on most top 40 radio stations.
However, Gaga recently stopped by "The Voice," where Christina Aguilera stepped in for an absent R. Kelly to complete the duet. Gaga released an official, slightly remixed version featuring Aguilera, which can be heard at right.
Which version do you prefer?
