In a candid recent interview, Harry Potter lead actor Daniel Radcliffe made the confession that he had a massive secret crush on one of his co-stars while filming the fantasy franchise as a teenager. While Radcliffe has cunningly remained coy without directly naming who his on-set infatuation was, multitudes of passionate Potter fans strongly suspect it was likely his lead co-star Emma Watson who captured his adolescent affections at the time based on deductive clues.

Radcliffe described harboring intense romantic feelings for one unnamed castmate but never working up the courage to admit it to her. His reveal has set off feverish speculation among devotees of the wizarding world that Watson was probably the subject of his years-long on-set infatuation.

While carefully not identifying his crush directly, Daniel Radcliffe provided tantalizing clues that it was another main Harry Potter cast member, describing having intense romantic feelings for a certain co-star during his tender teen years spent filming the movies. “I was infatuated with one of my co-stars, but I never told them,” Radcliffe admitted coyly.
