Winter may be coming, but Kit Harington and Rose Leslie's relationship is heating up!
The Game of Thrones stars -- who played star-crossed lovers Jon Snow and Ygritte on the popular HBO series -- were spotted packing on the PDA at The Grove in Los Angeles on Friday, seemingly confirming that they are, indeed, a couple.
According to the eyewitness, they stayed close to each other the entire time, exchanging kisses and being "very romantic."
These adorable snaps mark the first official sign of any PDA from the on-and-off screen couple. Though Harington and Leslie, 28, never confirmed it, it's been a longtime rumor that they've been dating on and off ever since meeting on the set of the fantasy drama TV series.
While -- SPOILER ALERT! -- Leslie's character, Ygritte, was shockingly killed by a young boy during a gruesome battle scene between the wildlings and crows at Castle Black in season four, the fate of her beloved Jon Snow is still to be determined.
Last year, HBO teased viewers with the possible resurrection of the fan-favorite when they released the first teaser trailer and poster from the all-new season. Hear more in the video below.
