Who is this girl and why is she pretending to be Ariana Grande?

With minimal photo research, it's easy to prove the pint-sized singer's face has gone through a shocking transformation over the years.

But lucky for her, the 21-year-old became really famous AFTER her looks drastically changed — so it's easy to forget this girl from 2008 who could easily pass for a very, very distant cousin of the 'Bang Bang' singer.

Don't believe us? Have a peek at the photos and see how much she's changed over the past few years — and you'll understand why fans have speculated if she's gone under the knife.
