Christina Aguilera Does a Spot-On Britney Spears Impression [VIDEO]

Oh baby, baby, Christina Aguilera nailed a Britney impression on The Tonight Show with Jimmy Fallon last night.

Christina is back on "The Voice" and making the talk show rounds including a stop at The Tonight Show, where she and Jimmy Fallon played the Wheel of Musical Impression.

When you play this game, you spin Jimmy's wheel and it lands on a song and a style. Christina and Jimmy went back and forth and it was pretty entertaining, but it got REALLY good when Christina lands on singing "This Little Piggy" in the style of Britney Spears, and she took us all back to the late 90s when the two popstars debuted.
