Vocal powerhouse Christina Aguilera has been using her gifted voice for various avenues – television shows, charity, and even voiceovers – but she now adds comedy to her resume. For her recent appearance on ‘The Tonight Show With Jimmy Fallon’, Christina was tasked with playing the ‘Wheel Of Musical Impressions’ game. She does a fair job of Cher singing the Folgers coffee jingle (0:35) and Shakira singing the ‘Golden Girls’ theme song (3:45), but its her impression of former rival Britney Spears that has caused the most attention. Taking on “This Little Piggy” (2:00) in Britney’s form, Christina delivers a solid vocal that actually pays homage to her biggest hit “Oops, I Did It Again”. Both Aguilera and Fallon laughed the entire time, and I’m certain Britney did exactly the same. Watch the hilarious clip featuring Christina Aguilera’s vocal impressions below.
