They will get hitched at Wardhill Castle in Aberdeenshire, which has been in Leslie's family for 900 years.
A date of June 23 was previously posted at Aberdeenshire's Huntly registration office.

Leslie left Game of Thrones two years after they met, while Harington has become one of the show's most popular stars.
"Because the country is lovely, because the Northern Lights are magical, and because it was there that I fell in love", he recalled.
The Good Fight actress Leslie said she had been too busy to plan the wedding, telling Town And Country magazine: "I haven't tackled it". It's nearly too much to handle - especially when you consider how damn goooOOoooooOOood he looks.
