Christina Aguilera was on "The Tonight Show" with Jimmy Fallon when they played a karaoke game that required them to impersonate famous singers. It was then that she mocked singers like Cher and even Britney Spears!!!

I am sure it was all out of fun, but Christina nailed it when she mocked our Louisiana girl, Britney Spears.

I also applaud her skills in mocking Cher and fellow judge on "The Voice," Shakira. You can even see just how surprised Jimmy Fallon was when Aguilera belted out the vocals from these artists.

Good stuff!!
