Lady Gaga and Christina Aguilera performing "Do What U Want

Are you ready for THE MOST FAKE PERFORMANCE EVER?

The Voice Xtina/Gaga duet looked forced af--it's sad that most viewers don't know it's just image maintenance for both of them. Fake as hell.

Lady Gaga and Christina Aguilera hit the stage together for the first time ever to perform “Do What U Want” live on The Voice Season 5 Finale on Tuesday (December 17) in Universal City, Calif.
