Christina Aguilera busts out impressions of Miley Cyrus, Cher, Britney, and more

We learned a couple months ago that Christina Aguilera has been working on her Britney Spears impression, but we didn't know she could handle Miley Cyrus, Cher, Shakira, and Sia too.

In this ad for “The Voice,” watch Christina ham it up as a handful of other divas. The Shakira impression is particularly stirring. Can we request an Ariana Grande impersonation next?
