Listen to Christina Aguilera's spot-on impression of Britney Spears' voice (Video)

Christina Aguilera and Britney Spears have a long history with each other. They’ve known each other since the early ‘90s when they co-starred on The Mickey Mouse Club together and now Aguilera proves she knows Spears’ voice better than anyone.

They were pitted against each other as rivals in their early days as pop stars in the 2000s, but Aguilera had some fun with it on Monday night.

The Voice mentor appeared on The Tonight Show and played the Wheel of Musical Impressions with host Jimmy Fallon. Spears’ name came up, paired with “This Little Piggy.”

With two kids now, Aguilera surely knows the lyrics. But it was her dead-on impression of Spears that has everyone talking.

Other impersonations she did were Shakira and her Burlesque co-star, Cher.

Aguilera will return to NBC’s The Voice for its eighth season after Shakira and Gwen Stefani filled in for her as she took a break.
