All of us have been told at some point while growing up that there is someone who looks exactly like us. Many others have a look-alike living right under the same roof, in the form of their twin sibling. Either way, it's always fun to know that there is someone who happens to weirdly look a lot like you. National Look-Alike Day, which is observed on April 20, is meant to identify and celebrate everyone who has a look-alike.

Having said that, the internet is flooded with examples of celebrity doppelgangers who took the likeness to the next level by becoming impersonators. To mark the occasion of the National Look-alike Day, here are some examples of such celeb look-alikes who will get you to rub your eyes and look again.
