Time passes unbelievably fast and leaves a mark on all of us. Some change for better, and some are almost unrecognizable. But take a look at this video. You will be shocked how some of the celebrities we all knew growing up have changed. Emma Watson is so beautiful, but someone will say that Jaden looks homeless. Elle and Dakota Fanning are gorgeous blonds now. See for yourself how the boy from the Two and a half men looks now. When you realize how old are they, you will be speechless.
