Returning The Voice judge Christina Aguilera is so talented she can do what those Internet impressionists do--but without the tech tricks. Aguilera really can do all the voices. On Jimmy Fallon, The Voice goddess begins with a freakishly accurate forgery of Cher singing the Folger's Coffee jingle.
Next Aguilera moves seamlessly on to her contemporary Britney Spears, singing "This Little Piggy." It's awesome. You might just go wee wee all the way home. Then there's Shakira. And Aguilera does it all without getting out of her chair. She's saving that, apparently, for The Voice.
