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.
Harington looked dapper in a fitted tee and dark-wash jeans while holding hands with Leslie, who kept it cool and casual in a turquoise maxi skirt and white blouse.
Much like the job of his GoT character, Harington, 29, kept a close watch -- on Leslie, his cell phone and shopping bags, that is!
An eyewitness tells ET that before the two shopped at Gap, J Crew and Nordstorm, they began their adventure with an hour-long lunch at Café Gratitude.
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.
