Last week, model Olga Vlasova alleged she had an affair with Harington after meeting the actor in Luxembourg in 2017 (when he was already engaged to Leslie) and again after their marriage in June. She also shared nude photos of a man she said was Harington.
Kit, 31, responded to the claims: "The allegations in this story are completely false," his told Entertainment Tonight. "[Harington] has never even been to Luxembourg nor has he ever met Olga Vlasova."
Harington and Leslie started dating while co-starring on GOT in 2012. They played love interests in seasons two through four of the HBO series and wed in June 2018.
