The pair, who play on-screen lovers Jon Snow and Ygritte in the HBO hit series, are reportedly a couple in real life as well. Both actors kept it casual for their trip to the airport, Harington was spotted in blue jeans and a blue t-shirt and Leslie in gray sweatpants and a white top.
While it is unclear where the pair was heading, the Daily Mail reports they were likely returning to London, where the two live.
In a clip shot by x17 online, Harington is asked to reveal "his favorite male accessory" after a paparazzi asks if his shoes are Jimmy Choo -- the actor recently posed in a series of ads for the brand.
Harington laughed and ignored the question before going about his day.
