Kit Harington and Rose Leslie are reportedly dating again.
The 'Game of Thrones' stars are said to have reconciled some time ago, almost a year after going their separate ways, but their rekindled romance isn't serious.
A source told Us Weekly magazine: ''They've been back on for about three months.
''That said, it's casual right now and they're having fun.''
Speculation the pair- who play Jon Snow and his lover Ygritte - had started once they were seen arriving together at Los Angeles International Airport ahead of appearing at the 'Game of Thrones' HBO panel at Comic-Con last month.
Both Kit and Rose are thought to be taking their renewed relationship slowly as the insider revealed they are not planning to take things to the next level just yet.
The source added: ''They're not moving in together or anything like that yet.''
Neither star has ever admitted to dating one another, but the 27-year-old actress did previously admit that her off-screen chemistry with Kit had helped when filming the more intense scenes together.
She shared: ''It's a wonderful perk when you're able to get on with your co-star, and Kit is a wonderful, wonderful man,
''He's very lovely, charming, sweet, and incredibly funny, so having that dialogue off-screen certainly pushes for the relationship they have on-screen. And if you're willing to trust the other person and allow them to play on-screen with the scene, it's a lovely attribute to have.''
