Celebs who drastically changed their looks after becoming famous

​Dwayne "The Rock" Johnson

Obviously, The Rock has had yet another breakthrough style evolution since the comparison pic on the right, taken in 2001. He's ditched the close-cropped hair, opting for the clean-shaven look, and upped his custom suit game to an enviable level. We're not sure if he still rocks the fanny pack, but we're pretty sure nobody would give him any crap about it if he does, since being jacked beyond belief is still an important component to his swagger.
