The Olsen Twins
Our list ends with a pair of the cutest child actors to ever step foot in Hollywood. The Olsen Twins were Hollywood regulars thanks to their work on Full House. Nowadays Mary-Kate and Ashley Olsen are focused entirely on their high fashion clothing line. We suppose being that close to fashion, and all of the models who smoke, has rubbed off on the normally wholesome Olsen twins. Mary-Kate and Ashley both have been caught smoking while out in public. Both Olsen twins are largely out of the acting world.
