We look at three mega stars who are hyper successful but who you may have never heard of. Romeo Santos is the king of bachata, Chicharito Hernandez is one of the most popular Mexican soccer players, and Bethany Mota is a  YouTube personality. They are all super stars in their respective worlds. And yet even though they sell out arenas in the U.S. and are making millions, they could probably walk around most neighborhoods in this country and not get recognized.
