Unless you've been living under a rock, you've likely come across a few (OK, dozens) of social media posts about Google's Arts & Culture app. Though the app was originally created so users could admire famous artworks at their fingertips, a brand-new feature has the internet up in arms: one that allows you to see your portrait painting doppelgängers in a matter of seconds.

So how exactly does this newly viral tool work? All you have to do is download the Google Arts & Culture app from either Google Play or the iTunes store, and scroll until you see the "Is your portrait in a museum?" feature, which prompts you to snap a quick selfie. Once it receives your snapshot, the app sifts through the thousands of artworks in its database and matches your face to a collection of supposedly similar paintings in side-by-side collages, along with the exact percentage of how much the two images resemble each other. Some are pretty spot on, while others are, er, a bit off, to say the least.

The app is pretty darn hysterical, especially because it'll match you with different portraits if you make a funny face in your selfie. As soon as people started catching wind of the addicting feature, a snowball effect took place, and seemingly the entire internet began sharing their artistic look-alikes - including celebrities. In case you need some motivation to finally delete some photos to free up space on your phone for the Google Arts & Culture app, allow these hilarious celeb 'grams and tweets to convince you.
