Watch Christina Aguilera impersonate Britney Spears
Christina Aguilera did a killer impression of Britney Spears during a visit to "The Tonight Show Starring Jimmy Fallon" on Monday.
Part of the game of "Wheel of Musical Impressions," Aguilera took on a song and a singer at random, which -- when combined --sounded pretty darn good.
The "Voice" coach kicked things off with an impression of Cher singing the Folger's Coffee theme song. And then she took it up a notch with an impression of fellow Disney Mousketeer Spears singing "The Little Piggy.
Fallon got in on the action, too, with impressions of Michael McDonald and David Bowie.
"That was something I've always wanted to do, that was amazing," Fallon said. "I love that so much, that was fantastic!"
