This is seriously the best thing on the Internet today!

Christina Aguilera appeared on The Tonight Show with Jimmy Fallon yesterday evening, and the singer and the talk show host played "wheel of musical impressions" whereby Xtina belted out a truly jaw-dropping rendition of "This Little Piggy" in her best Britney Spears voice.

The blonde bombshell also treated the audience to her version of Cher singing the Folger's coffee jingle. You have to watch this video!
