Emilia Clarke and Nikolaj Coster-Waldau, both stars of "Game of Thrones," have portrayed characters with a complex relationship, but there is no public record or credible source indicating they dated. In contrast, Clarke has been linked romantically to her other co-stars, such as Jason Momoa, Kit Harington, and Iain Glen. Their on-screen chemistry did not translate into a real-life relationship, making Coster-Waldau the only co-star she did not date.
