Game of Thrones' Kit Harington, Rose Leslie indulge in PDA
The former flames were seen holding hands and even shared a kiss, reported People magazine.
According to onlookers, at one point Leslie peeped over Harington's phone, resting her head on his shoulder.
The duo first sparked dating rumours in 2012, when their on-screen characters came close, though it ended in a year.
However, the recent sightings have rekindled the speculation of their real-life romance.
