Emilia Clarke has reportedly split from boyfriend Seth MacFarlane. E! News reports that the two called things off due to their "location challenge." Last night, Emilia donned a blue dress by Victoria Beckham and mingled with her former costar Jason Momoa on the red carpet at HBO's Game of Thrones premiere party in LA. Meanwhile, Lena Headey ditched the long blond locks she is famous for on the show for a brunette 'do, and stars Richard Madden, Kit Harington, and Peter Dinklage sported dapper suits for the big event. Emilia reportedly skipped the afterparty so that she could fly back to New York to prepare for her upcoming stint on Broadway in Breakfast at Tiffany's.
