Hollywood power couple Calvin Harris and Taylor Swift are to get married at an exclusive Scottish castle, it has been claimed. 

The couple, who recently celebrated their one year anniversary on March 6, are understood to have selected Wedderburn Castle near Duns in the Scottish Borders as their venue of choice.

A spokeswoman for the castle said the venue is "exclusive, discreet and personal," and would not comment on the wedding.

A source has told Hollywood Life said 26-year-old Swift has even picked the type of engagement ring she wants and a designer for her dress. 

The source said: "She says she’d love Elie Saab to design a very simple yet elegant gown.

“She wants it to be figure-hugging and made of lace.”  

“Taylor’s already told Calvin that she wants Lorraine Schwartz to design her engagement ring. She has her heart set on a square-cut diamond similar to Beyonce‘s, but with a more vintage twist.” 

Superstar DJ Harris, whose real name is Adam Wiles, grew up in the Dumfries surburb of Georgetown before hitting the dizzy heights of fame with hits We Found Love and Summer. 

The 32-year-old recently gave American popstar girlfriend Swift an engraved locket to celebrate their first year together.

The songstress shared an image of the locket with fans on her Instagram account with the caption, "3.6.15 One year down."

The pair also recently shared snaps of a romantic getaway and the Bad Blood singer even posted a pic of their initials written in the white sand.

She captioned it: “Taylor Swift + Adam Wiles” in reference to the DJ’s real name.

Harris is due back in Scotland in the summer to headline T in the Park at Strathallan Castle on Saturday, July 9.
