"Sex Education" star Emma Mackey has spoken out about people comparing her to fellow actress Margot Robbie and has revealed she doesn't think she looks "anything like" the Australian star. Fans have long been claiming the pair are indistinguishable and, we have to admit, we do see the resemblance. Plus, both are set to star in Greta Gerwig's upcoming "Barbie" film, and some have speculated that they'll both be playing a version of the titular doll due to their similar appearance.
