There’s no question that Christina Aguilera can hit the high notes, but who knew the pop star was a master impersonator, too?

While promoting the upcoming season of “The Voice” on “The Tonight Show” Monday, Aguilera was challenged by host Jimmy Fallon to a few rounds of “Wheel of Musical Impressions.”

Channeling her inner Cher, the blond bombshell belted out the sultriest rendition of the Folgers theme song, before tackling “This Little Piggy” as her former co-Mouseketeer Britney Spears.

Aguilera’s spot-on vocals of Spears not only garnered plenty of cheers from the audience, but a standing ovation from Fallon, who could barely contain his excitement.

“That is something I’ve always wanted to see, that was amazing,” exclaimed Fallon. “It’s hard to top that.”

Up for the challenge, Brit?
