Watch Christina Aguilera Impersonate Miley Cyrus, Cher and More!

Turns out Christina Aguilera doesn't just do spot-on impressions of Britney Spears and Sex and the City's Samantha Jones!
In a new promo for The Voice, the "Dirrty" singer served up her best imitations of fellow pop stars, Miley Cyrus, Sia, Cher, Shakira, and Spears (again).
Perhaps her best impression was of her Burlesque co-star. Donning the pop legend's iconic, scantily-clad outfit, Aguilera (as Cher) made jokes at her fellow Voice team leaders' expense, mispronouncing Blake Shelton's name and inquiring as to whether Adam Levine was her accountant.
Xtina's impersonation of Spears on The Tonight Show starring Jimmy Fallon is still a favorite. Check it out:
