Lady Gaga and Christina Aguilera performed together for the first time on The Voice! (It was actually the first time the two artists have ever met!)
When Gaga got the call to perform on The Voice, she said she would only do it if Aguilera performed with her.
They sound great together, wore matching outfits, and cuddled and drank champagne on stage :-)
