Who wouldn’t want to be a fly on the wall during a recording session for Lady Gaga and R. Kelly’s new duet “Do What U Want?”; The song, which will appear on Lady Gaga’s forthcoming record ARTPOP, got a 30-second tease during a new Best Buy commercial promoting the popular Beats By Dre headphones. Set to seriously sexy close-ups of the headphones, hear Gaga tell Kells to “do what you want to my body.”; The frothy R&B jam sounds spectacular, and we might take the headphones, too.
