There are a lot of famous people we confuse for one another: Katy Perry and Zooey Deschanel; Bill Paxton and Bill Pullman; Tom Hanks and Dr. Dre. But this mostly comes from faulty recollection rather than some bizarre experiment that resulted in two famous people that look almost exactly alike.
Which is pretty much what we're guessing happened with the celebrities our readers found below. Pretty much, you could interchange one for the other and no one would ever be the wiser.
