Ariana Grande Vs. Charli XCX: Whose Britney Impression Truly Slays?

You better vote, vote.

Pitting two famous women against each other is a cheap, lazy tactic often employed by the media to reinforce the notion that women are always in competition with each another. That said, can we talk how unexpectedly good Ariana Grande and Charli XCX both are at impersonating Britney Spears?

Here's Ari singing "I'm Not A Girl, Not Yet A Woman," courtesy of a nearly 3-year-old YouTube video.

And here's the "Doing It" singer tackling "I'm A Slave 4 U," "...Baby One More Time" and "Work Bitch" on the U.K.'s Capital FM last week.

The vocal fry! The growl! Both ladies captured Brit's je ne sais quoi-ney with ease, but whose impression takes the cake green tea frappuccino? Vote in the poll below.
