BERKSHIRE, UK: Game of Thrones star Natalie Dormer has called off her wedding to fiance Anthony Byrne. Friends say that Natalie blames her hectic work schedule for the U-turn and although her spokesman insists the couple are still together, sources claim they have barely seen each other in months. Natalie, 31, rose to fame last year playing manipulative Margaery Tyrell in the TV smash hit Game Of Thrones and her acting career has gone from strength to strength ever since.
