Returning "The Voice Season 8" coach Christina Aguilera surprised everyone when she nailed impressions of her once singing rival Britney Spears as well as Cher and Shakira.
When she appeared on the Feb. 23, Monday, episode of "The Tonight Show," Aguilera and host Jimmy Fallon competed in a game called "Wheel of Musical Impressions," in which a musical impressions generator randomly chooses an artist and pairs it up with a song.
While Fallon was trained to imitate musicians with his background as a "Saturday Night Live" alum, it appears that his performance was not great enough to match Aguilera's.
Aguilera started with a Cher impersonation singing a rendition of the "Folgers Coffee" jingle followed by Fallon's "Grand Old Flag" performance as David Bowie.
The climax of the "The Tonight Show" segment "Wheel of Musical Impressions" during that Feb. 23, Monday, episode, however, appears to be that moment when Aguilera sang "This Little Piggy" to the tune of "Baby One More Time" in the style of Spears, her former rival as a pop star in the 1990s.
Aguilera's Spears impression was so good that Fallon gave her a standing ovation.
In addition, Aguilera sang the "Golden Girls" theme song in the style of Shakira with a few "lole lole" ad libs as Fallon jumped in as Michael McDonald.
On the same day, Aguilera reunited with bromance partners Blake Shelton and Adam Levine as "The Voice" judge. Also joining them as a judge on the NBC's singing competition is "Happy" hitmaker Pharrell Williams.
For Aguilera, mentoring on "The Voice" was great and there is no pressure.
"I showed up, saw a good friend, and watched and guided her team for the day, and left," Aguilera told The Hollywood Reporter. "I really loved it, as the pressure was not on me."
Also, the mother of two is set to play a pop star who moves to Music City to reinvent herself as a country singer on ABC's "Nashville," Rolling Stone has learned.
