They reportedly broke up in 2013, but things may be back on for former Game of Thrones co-stars Kit Harington and Rose Leslie.

Kit Harington Finally Reveals Jon Snow's Fate

The former co-stars and couple were spotted arriving in Los Angeles together last night, and though the two didn't hold hands or display any affection as they walked through LAX with Sophie Turner, they were spotted getting close again in London earlier this week.

Perez Hilton was the first to report on the couple being seen together again in London, where they allegedly dined together at a new restaurant in Soho and acted "coupley" during their meal, with Leslie even ruffling her hands through Harington's hair at one point.

The couple has reportedly been on and off for several years, and were reported to have broken up in 2013. However, they've since been spotted getting cozy again on and off since then.

The two were an on-screen pairing on the hit HBO series in the second and third seasons, with their characters Jon Snow and Ygritte becoming a couple while Jon was under cover with the Wildlings. However, things soured after his escape, and the two remained apart until the penultimate episode of season four, when the Wildlings attacked Castle Black. The two came face-to-face and an angry Ygritte was prepared to kill him for his betrayal when Ollie shot her in the chest with an arrow. Following the battle, Jon took her body into the woods and burned it.

The season five finale of the show had a similarly themed ending, however, when Jon appeared to die after he was betrayed by his brothers in the Night's Watch, who stabbed him repeatedly due to their opposition of his plan to bring the Wildlings behind the Wall for protection. The one to deliver the final blow in that situation was also Ollie.
