Game of Thrones stars Kit Harington and Rose Leslie are due to marry in the north east of Scotland on Saturday.
The couple – who played on-screen lovers Jon Snow and Ygritte – met on the fantasy show in 2012.
The wedding will take place at Wardhill Castle, owned by actress’s father, Seb Leslie.
Speaking outside the castle, Mr Leslie, an Aberdeenshire councillor, said he was “absolutely thrilled” for the couple on their big day.
He added: “It’s an absolutely lovely day for us.”
Fellow Game of Thrones cast members Emilia Clarke – Daenerys Targaryen – and Peter Dinklage, who plays Tyrion Lannister, arrived in Aberdeen on Friday.
The engagement was announced last September.
The actress grew up in Aberdeenshire before moving to London to pursue her career.

The couple have often been seen together in the north east of Scotland.
The 23 June date was posted at the Huntly registration office last month.
Leslie left the cast two years after they met, while Harington has appeared in every series of the popular TV drama, becoming one of the show’s biggest stars.
Harington told L’Uomo Vogue it was “easy” to fall in love with his co-star.
He said his best memory of the show was three weeks in Iceland when they filmed the second season.
“Because the country is beautiful, because the Northern Lights are magical, and because it was there that I fell in love,” he recalled.
“If you’re already attracted to someone, and then they play your love interest in the show, it becomes very easy to fall in love.”
