They are set to get married later this month, after announcing their engagement in September last year.
And it seems like Kit Harington and Rose Leslie, both 31, will have quite a unique wedding ceremony as they are said to have hired a hooded Benedictine monk to officiate.
Their interesting choice of nuptials will be a nod to how they met on Game Of Thrones, a source told The Sun on Friday: 'They're getting married by a monk in a castle. It doesn't get more Game of Thrones than that.'

'When you think about how they met, it's perfect,' the source continued about their choice of plans.
Kit's character Jon Snow first met the wildling girl Ygritte, played by Rose, while travelling north of The Wall as part of the Night's Watch, and although they were on opposing sides it didn't take long before they fell in love.
Kit and Rose announced their engagement in The Times newspaper in September, and of their special service the source said: 'They were delighted to meet Father Chad, who's really looking forward to the big day.
