Kit Harrington, who played Jon Snow in the hugely successful Game of Thrones for 8 years, checked himself into rehab. The show coming to an end hit the 32 year old very hard. The British actor entered the luxury Connecticut health retreat Privé-Swiss for nearly a month, beginning weeks before the show’s finale on May 19. Harrington's wife Rose Leslie, who played Ygritte on GoT, supports him 100%.
