Lady Gaga And Christina Aguilera Record Duet
Mother Monster shares audio of Do What U Want on internet...
The pop stars first collaborated on the track on The Voice in the US - and the reception was so good that they decided to head into the studio to lay down an official version.
Now Gaga has posted the track on YouTube and it had already garnered more than 100,000 views at the time of writing, just 24 hours after it was posted.
Gaga had originally recorded the track - and had a hit - with R&B star R Kelly.
