Christina Aguilera Kills This Britney Spears Impression: Watch

No beef, no bacon, just pure 'wee wee all the way home' madness.

Beef? What beef? (Or is it bacon?) "The Voice" coach Christina Aguilera dropped by "The Tonight Show" on Monday and got roped into playing host Jimmy Fallon's "Random Music Impressions" game. And, shocker, among the names that, ahem, "randomly" came up was none other than her one-time pop chart rival, Britney Spears.

"Britney!," Christina said when the screen showed Spears' name and "This Little Piggy" as her selection. "You know Britney Spears, right?" Fallon asked as Aguilera laughed. "Lil bit, Lil bit."

It took her a second, but then Christina, oh baby, baby, she nailed it.

The killer impression came after Xtina had to fight through some truly random selections, including a soulful take on Cher singing a the Folgers coffee jingle and Shakira shaking out the "Golden Girls" theme song.
