Have you ever wondered how your favorite actors or singers would look like in a few years? Thanks to the new FaceApp old age challenge you can get a sense of it! The photo editing app uses an age filter which basically adds grey hair and wrinkles to someone's picture.

FaceApp became really popular in the last few days. Some of our favorite stars have been having a lot of fun with it and have shared their pictures on Instagram so fans can see how they would look in a couple of years or even decades!
