Christina Aguilera Absolutely Crushes Impressions Of Other Celebrities (Video)

Christina Aguilera has been known to bust out an impression from time to time.

Now, she's done a whole bunch of them in a special sketch for the season finale of "The Voice."

Aguilera lampooned many of her fellow pop stars in hilarious fashion in this bit.

She took on such musical icons as Britney Spears, Miley Cyrus, Shakira, Lady Gaga and Cher. She even dressed in a ridiculous Sia outfit and had a little mini version of Sia right beside her.

The sketch is pretty excellent, so be sure to give it a look up above.
